-Object: Provide a Hook on Alsa PCM to check permission again AGL Advance Audio Agent
-Status: Release Candidate
-Author: Fulup Ar Foll fulup@iot.bzh
-Date  : August-2017
-
-Functionalities:
- - Execute a set of websocket RPC request again AGL binders to allow/deny access
- - Keep websocket open in an idepandant thread on order to monitor event receive from AGL audio agent
-
-Installation
- - Alsaplugins are typically search in /usr/share/alsa-lib. Nevertheless a full path might be given
- - This plugin implement a hook on a slave PCM. Typically this slave PCM is a dedicated virtual channel (eg: navigation, emergency,...)
- - Config should be place in ~/.asoundrc (see config sample in PROJECT_ROOT/conf.d/alsa)
-
-Test
- - Install a full .asoundrc from conf.d/project/alsa.d
- - speaker-test -DMyNavigationHook -c2 -twav
-
-Config
-```
-# Define sharelib location and entry point
-# -----------------------------------------
-pcm_hook_type.MyHookPlugin {
-    install "AlsaInstallHook"
-    lib "/home/fulup/Workspace/AGL-AppFW/audio-bindings-dev/build/Alsa-Plugin/Alsa-Hook-Callback/alsa_hook_cb.so"
-}
-
-# Create PCM HOOK with corresponding request calls to AGL Audio Agent
-# --------------------------------------------------------------------
-pcm.MyNavigationHook {
-    type hooks
-    slave.pcm "MyMixerPCM"
-
-    # Defined used hook sharelib and provide arguments/config to install func
-    hooks.0 {
-        type "MyHookPlugin"
-        hook_args {
-            verbose true # print few log messages (default false);
-
-            # Every Call should return OK in order PCM to open (default timeout 100ms)
-            uri   "ws://localhost:1234/api?token='audio-agent-token'"
-            request {
-                # Request autorisation to write on navigation
-                navigation-ctl {
-                    api   "control"
-                    verb  "dispatch"
-                    args   "{'target':'navigation', 'args':{'device':'Jabra SOLEMATE v1.34.0'}}"
-                }
-                # subscribe to Audio Agent Event map them to signal
-                subscribe-evt {
-                    api   "control"
-                    verb  "monitor"
-                }
-            }
-            # map event reception to self generated signal
-            event {
-                pause  30
-                resume 31
-                stop   3
-            }
-        }
-    }
-}
-
-```
-
-NOTE:
-
-* Hook plugin is loaded by Alsa libasound within player context. It inherits client process attributes, as UID/GID or
-the SMACK label on AGL. This smack label is tested by AGL security framework when requested a call on the audio-agent binder.
-As a result the call will only succeed it the permission attached the application in Cynara matches.
-
-* Hook plugin keep a connection with the Audio-Agent until PCM is closed by the application. This connection allow the
-Audio-Agent to send events. eg: pause, quit, mute, ...

-Object: Add virtual soft control to sound card
-Status: Proof of concept and not a usable product
-Author: Fulup Ar Foll
-Date  : June-2017
-
-HAL-plugin allows:
- - to expose any existing NUMID under a customized label name, this is order to abstract sound card config.
- - to add non alsa NUMID supported through a callback mechanism (eg: volume rampdown, power off, ...)
-
-installation
- - Plugin should be placed where ever alsaplugins are located (typically: /usr/share/alsa-lib)
- - Callback sharelib directory should be declare in $LD_LIBRARY_PATH
-
-Config
-```
-cat ~/.asoundrc
-  ctl.agl_hal {
-    type  afbhal
-    devid "hw:4"
-    cblib "afbhal_cb_sample.so"
-    ctls {
-        # ctlLabel {numid integer name "Alsa Ctl Name"}
-        MasterSwitch { numid 4 name "My_First_Control" }
-        MasterVol    { numid 5 name "My_Second_Control" }
-        CB_sample    { ctlcb @AfbHalSampleCB name "My_Sample_Callback"}
-    }
-    pcm.agl_hal {
-        type copy     # Copy PCM
-        slave "hw:4"  # Slave name
-  }
-```
-
-With such a config file
- - numid=4 from sndcard=hw:4 is renamed "My_First_Control"
- - numid=4 from sndcard=hw:4 is renamed "My_Second_Control"
- - numid=4 will call AfbHalSampleCB from afbhal_cb_sample.so
-
-Note: to really implement a usable HAL at minimum every ALSA call should be implemented and read/write of values should be normalised from 0 to 100% with a step of 1.
-
-Conclusion: This demonstrate that implementing a HAL that both abstract ALSA get/set and enable non ALSA support is possible at an acceptable cost
-without having to hack ALSA source code. The beauty of the model is than it is fully transparent to any ALSA application. The limit is that the plugin is loaded
-within every application context, thus interaction with an external event loop remains complete as well as conflict management in case of share resources.

-# HAL for MOST Sound Card
-
-## Introduction
-This Hardware Abstraction Layer (HAL) is intended to control MOST audio via
-standard ALSA mixer controls. Therefore the HAL add's controls to the MOST sound
-card. Modification of the mixer controls is mapped to control commands which are
-send to MOST nodes.
-
-The HAL requires to access the UNICENS V2 binding which is setting up the MOST
-network and the MOST node.
-
-Please check the following required components:
-* MOST Linux Driver
-* User must be member of "audio" group
-* UNICENS V2 binding
-* [K2L MOST150 Audio 5.1 Kit](https://www.k2l.de/products/74/MOST150%20Audio%205.1%20Kit/)
-
-## Possible Modifications
-Check if you need to adapt the default path for UNICENS configuration, e.g.
-```
-#define XML_CONFIG_PATH "/opt/AGL/unicens2-binding/config_multichannel_audio_kit.xml"
-```
-
-Check if you need to adapt the name of the MOST sound card.
-```
-#define ALSA_CARD_NAME  "Microchip MOST:1"
-```
-
-You can check your MOST sound card name by calling ```aplay -l```, e.g.
-```
-aplay -l
-**** List of PLAYBACK Hardware Devices ****
-card 0: PCH [HDA Intel PCH], device 0: 92HD90BXX Analog [92HD90BXX Analog]
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-card 1: ep016ch [Microchip MOST:1], device 0: ep01-6ch []
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-card 2: ep022ch [Microchip MOST:2], device 0: ep02-2ch []
-  Subdevices: 1/1
-  Subdevice #0: subdevice #0
-
-```
-Choose the first sound card with 6 channels, e.g. if you see ```ep01-6ch``` just
-take ```Microchip MOST:1```.
-
-If you get messed up with card enumeration the following action may help:
-- Unplug your MOST USB hardware from target
-- Call ```sudo rm /var/lib/alsa/asound.state```
-- Connect MOST USB hardware after reboot or restart of ALSA

-WRAP-JSON facility

-==================

-

-The facility wrap-json is based on the pack/unpack API on the

-libray jansson. The two chapters below are copied from the

-documentation of jansson library copyrighted by Petri Lehtinen

-(see at end).

-

-Building Values

----------------

-

-This section describes functions that help to create, or *pack*, complex

-JSON values, especially nested objects and arrays. Value building is

-based on a *format string* that is used to tell the functions about the

-expected arguments.

-

-For example, the format string `"i"` specifies a single integer value,

-while the format string `"[ssb]"` or the equivalent `"[s, s, b]"`

-specifies an array value with two strings and a boolean as its items:

-

-    /* Create the JSON integer 42 */

-    wrap_json_pack(&result, "i", 42);

-

-    /* Create the JSON array ["foo", "bar", true] */

-    wrap_json_pack(&result, "[ssb]", "foo", "bar", 1);

-

-Here's the full list of format specifiers. The type in parentheses

-denotes the resulting JSON type, and the type in brackets (if any)

-denotes the C type that is expected as the corresponding argument or

-arguments.

-

-`s` (string) \[const char \*\]

-

-:   Convert a null terminated UTF-8 string to a JSON string.

-

-`s?` (string) \[const char \*\]

-

-:   Like `s`, but if the argument is *NULL*, output a JSON null value.

-

-`s*` (string) \[const char \*\]

-

-:   Like `s`, but if the argument is *NULL*, do not output any value.

-    This format can only be used inside an object or an array. If used

-    inside an object, the corresponding key is additionally suppressed

-    when the value is omitted. See below for an example.

-

-`s#` (string) \[const char \*, int\]

-

-:   Convert a UTF-8 buffer of a given length to a JSON string.

-

-`s%` (string) \[const char \*, size\_t\]

-

-:   Like `s#` but the length argument is of type size\_t.

-

-`+` \[const char \*\]

-

-:   Like `s`, but concatenate to the previous string. Only valid after

-    `s`, `s#`, `+` or `+#`.

-

-`+#` \[const char \*, int\]

-

-:   Like `s#`, but concatenate to the previous string. Only valid after

-    `s`, `s#`, `+` or `+#`.

-

-`+%` (string) \[const char \*, size\_t\]

-

-:   Like `+#` but the length argument is of type size\_t.

-

-`n` (null)

-

-:   Output a JSON null value. No argument is consumed.

-

-`b` (boolean) \[int\]

-

-:   Convert a C int to JSON boolean value. Zero is converted to `false`

-    and non-zero to `true`.

-

-`i` (integer) \[int\]

-

-:   Convert a C int to JSON integer.

-

-`I` (integer) \[json\_int\_t\]

-

-:   Convert a C json\_int\_t to JSON integer.

-

-`f` (real) \[double\]

-

-:   Convert a C double to JSON real.

-

-`o` (any value) \[json\_t \*\]

-

-:   Output any given JSON value as-is. If the value is added to an array

-    or object, the reference to the value passed to `o` is stolen by the

-    container.

-

-`O` (any value) \[json\_t \*\]

-

-:   Like `o`, but the argument's reference count is incremented. This is

-    useful if you pack into an array or object and want to keep the

-    reference for the JSON value consumed by `O` to yourself.

-

-`o?`, `O?` (any value) \[json\_t \*\]

-

-:   Like `o` and `O`, respectively, but if the argument is *NULL*,

-    output a JSON null value.

-

-`o*`, `O*` (any value) \[json\_t \*\]

-

-:   Like `o` and `O`, respectively, but if the argument is *NULL*, do

-    not output any value. This format can only be used inside an object

-    or an array. If used inside an object, the corresponding key is

-    additionally suppressed. See below for an example.

-

-`[fmt]` (array)

-

-:   Build an array with contents from the inner format string. `fmt` may

-    contain objects and arrays, i.e. recursive value building is

-    supported.

-

-`{fmt}` (object)

-

-:   Build an object with contents from the inner format string `fmt`.

-    The first, third, etc. format specifier represent a key, and must be

-    a string (see `s`, `s#`, `+` and `+#` above), as object keys are

-    always strings. The second, fourth, etc. format specifier represent

-    a value. Any value may be an object or array, i.e. recursive value

-    building is supported.

-

-Whitespace, `:` and `,` are ignored.

-

-More examples:

-

-    /* Build an empty JSON object */

-    wrap_json_pack(&result, "{}");

-

-    /* Build the JSON object {"foo": 42, "bar": 7} */

-    wrap_json_pack(&result, "{sisi}", "foo", 42, "bar", 7);

-

-    /* Like above, ':', ',' and whitespace are ignored */

-    wrap_json_pack(&result, "{s:i, s:i}", "foo", 42, "bar", 7);

-

-    /* Build the JSON array [[1, 2], {"cool": true}] */

-    wrap_json_pack(&result, "[[i,i],{s:b}]", 1, 2, "cool", 1);

-

-    /* Build a string from a non-null terminated buffer */

-    char buffer[4] = {'t', 'e', 's', 't'};

-    wrap_json_pack(&result, "s#", buffer, 4);

-

-    /* Concatenate strings together to build the JSON string "foobarbaz" */

-    wrap_json_pack(&result, "s++", "foo", "bar", "baz");

-

-    /* Create an empty object or array when optional members are missing */

-    wrap_json_pack(&result, "{s:s*,s:o*,s:O*}", "foo", NULL, "bar", NULL, "baz", NULL);

-    wrap_json_pack(&result, "[s*,o*,O*]", NULL, NULL, NULL);

-

-Parsing and Validating Values

------------------------------

-

-This section describes functions that help to validate complex values

-and extract, or *unpack*, data from them. Like building values

-&lt;apiref-pack&gt;, this is also based on format strings.

-

-While a JSON value is unpacked, the type specified in the format string

-is checked to match that of the JSON value. This is the validation part

-of the process. In addition to this, the unpacking functions can also

-check that all items of arrays and objects are unpacked. This check be

-enabled with the format specifier `!` or by using the flag

-`JSON_STRICT`. See below for details.

-

-Here's the full list of format specifiers. The type in parentheses

-denotes the JSON type, and the type in brackets (if any) denotes the C

-type whose address should be passed.

-

-`s` (string) \[const char \*\]

-

-:   Convert a JSON string to a pointer to a null terminated UTF-8

-    string. The resulting string is extracted by using

-    json\_string\_value() internally, so it exists as long as there are

-    still references to the corresponding JSON string.

-

-`s%` (string) \[const char \*, size\_t \*\]

-

-:   Convert a JSON string to a pointer to a null terminated UTF-8 string

-    and its length.

-

-`n` (null)

-

-:   Expect a JSON null value. Nothing is extracted.

-

-`b` (boolean) \[int\]

-

-:   Convert a JSON boolean value to a C int, so that `true` is converted

-    to 1 and `false` to 0.

-

-`i` (integer) \[int\]

-

-:   Convert a JSON integer to C int.

-

-`I` (integer) \[json\_int\_t\]

-

-:   Convert a JSON integer to C json\_int\_t.

-

-`f` (real) \[double\]

-

-:   Convert a JSON real to C double.

-

-`F` (integer or real) \[double\]

-

-:   Convert a JSON number (integer or real) to C double.

-

-`o` (any value) \[json\_t \*\]

-

-:   Store a JSON value with no conversion to a json\_t pointer.

-

-`O` (any value) \[json\_t \*\]

-

-:   Like `O`, but the JSON value's reference count is incremented.

-

-`[fmt]` (array)

-

-:   Convert each item in the JSON array according to the inner format

-    string. `fmt` may contain objects and arrays, i.e. recursive value

-    extraction is supported.

-

-`{fmt}` (object)

-

-:   Convert each item in the JSON object according to the inner format

-    string `fmt`. The first, third, etc. format specifier represent a

-    key, and must be `s`. The corresponding argument to unpack functions

-    is read as the object key. The second fourth, etc. format specifier

-    represent a value and is written to the address given as the

-    corresponding argument. **Note** that every other argument is read

-    from and every other is written to.

-

-    `fmt` may contain objects and arrays as values, i.e. recursive value

-    extraction is supported.

-

-`!`

-

-:   This special format specifier is used to enable the check that all

-    object and array items are accessed, on a per-value basis. It must

-    appear inside an array or object as the last format specifier before

-    the closing bracket or brace.

-

-`*`

-

-:   This special format specifier is the opposite of `!`. This is the default.

-    It must appear inside an array or object as the last format specifier

-    before the closing bracket or brace.

-

-Whitespace, `:` and `,` are ignored.

-

-Examples:

-

-    /* root is the JSON integer 42 */

-    int myint;

-    wrap_json_unpack(root, "i", &myint);

-    assert(myint == 42);

-

-    /* root is the JSON object {"foo": "bar", "quux": true} */

-    const char *str;

-    int boolean;

-    wrap_json_unpack(root, "{s:s, s:b}", "foo", &str, "quux", &boolean);

-    assert(strcmp(str, "bar") == 0 && boolean == 1);

-

-    /* root is the JSON array [[1, 2], {"baz": null} */

-    wrap_json_check(root, "[[i,i], {s:n}]", "baz");

-    /* returns 0 for validation success, nothing is extracted */

-

-    /* root is the JSON array [1, 2, 3, 4, 5] */

-    int myint1, myint2;

-    wrap_json_unpack(root, "[ii!]", &myint1, &myint2);

-    /* returns -1 for failed validation */

-

-    /* root is an empty JSON object */

-    int myint = 0, myint2 = 0, myint3 = 0;

-    wrap_json_unpack(root, "{s?i, s?[ii]}",

-                "foo", &myint1,

-                "bar", &myint2, &myint3);

-    /* myint1, myint2 or myint3 is no touched as "foo" and "bar" don't exist */

-# AFB-daemon dependencies
 
-OpenSuse >=42.2, Fedora>=25, Ubuntu>=16.4 AGL Binary packages installation from
-[this wiki](https://en.opensuse.org/LinuxAutomotive)
-
-For other distro see chapter [# Building AFB-daemon from source on Standard Linux Distribution](#Build)
-
-# Specific Dependencies
-
-* alsa-devel >= 1.1.3 Warning some distro like Fedora 25 still ship version 1.1.1 as default
-
-> **NOTE**: On Ubuntu 16.4 you should recompile AlsaLib from [source](ftp://ftp.alsa-project.org/pub/lib/)
-> as today latest stable is 1.1.4.
-
-  OpenSuse
-     - Alsa-devel ```zypper install alsa-devel # 42.3 is shipped default with 1.1.4```
-
-  Fedora 26 (out of the box)
-     - Alsa-devel 1.1.4
-
-  Ubuntu-16.4
-     - Alsa should be recompiled from source
-
-```bash
-wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.1.4.1.tar.bz2
-tar -xjf alsa-lib-1.1.4.1.tar.bz2
-cd alsa-lib-1.1.4.1
-./configure --prefix=/opt
-```
-
-  Ubuntu-17.04 (out of the box)
-     - Alsa 1.1.4
-
-> **WARNING**: do not forget to upgrade your PKG_CONFIG_PATH=/opt/lib/pkgconfig
-> or whatever is the place where your installed alsa.
-
-# Compile AGL-Advanced-Audio-Agent
-
-* Edit your ~/.config/app-templates/cmake.d/00-common-userconf.cmake to reflect
- your local configuration
-
-```cmake
-    message(STATUS "*** Fulup Local Config For Native Linux ***")
-    add_compile_options(-DNATIVE_LINUX)
-
-    set (RSYNC_TARGET "10.20.101.198")
-    set (RSYNC_PREFIX "opt")
-
-    set(CMAKE_INSTALL_PREFIX $ENV{HOME}/opt)
-    set(BINDINGS_INSTALL_PREFIX $ENV{HOME}/opt)
-
-    set(CMAKE_PREFIX_PATH ${CMAKE_INSTALL_PREFIX}/lib64/pkgconfig ${CMAKE_INSTALL_PREFIX}/lib/pkgconfig)
-    set(LD_LIBRARY_PATH ${CMAKE_INSTALL_PREFIX}/lib64 ${CMAKE_INSTALL_PREFIX}/lib)
-
-```
-
-```bash
-    mkdir -p build
-    cd build
-    cmake -DCMAKE_INSTALL_PREFIX=$INSTALL_PREFIX ..
-    make
-
-    # Note: 
-      1) Controller is now a standalone project and should added on top of project bindings
-      2) If you want monitoring add '--alias=/monitoring:$HOME/opt/afb-monitoring'  (should point to monitoring HTML5 pages)
-      3) To expose AAAA control interface add '--ws-server=unix:/var/tmp/afb-ws/ctl-aaaa'
-
-    afb-daemon --workdir=. --ldpaths=. --binding=../../afb-controller/build/afb-source/afb-control-afb.so --port=1234  --roothttp=../htdocs --token="" --verbose
-    
-
-    Warning: See below net on GDB requiring (--workdir=.)
-```
-
-# Note: GDB Source Debug limits/features
-
-Warning: technically AGL bindings are shared libraries loaded thought 'dlopen'. GDB supports source debug of dynamically
-loaded libraries, but user should be warn that the actual path to sharelib symbols is directly inherited from DLOPEN.
-As a result if you change your directory after binder start with --workdir=xxx then GDB will stop working.
-
-Conclusion: double-check that --workdir=. and run debug session from ./build directory. Any IDEs like Netbeans or VisualCode should work out of the box.
-
-```bash
-    Examples:
-
-    # WORK when running in direct
-    afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
-
-    # FAIL when using GDB with warning: Could not load shared library ....
-    gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
-    ...
-    warning: Could not load shared library symbols for ./build/ucs2-afb/afb-ucs2.so.
-    Do you need "set solib-search-path" or "set sysroot"?
-    ...
-```
-
-To debug sharelib symbol path: start your binder under GDB. Then break your session after the binder has
-loaded its bindings. Finally use "info sharedlibrary" and check 'SymsRead'. If equal to 'No' then either you start GDB
-from the wrong relative directory, either you have to use 'set solib-search-path' to force the path.
-
-```bash
-    gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
-    run
-        ...
-        NOTICE: API UNICENS added
-        NOTICE: Waiting port=1234 rootdir=.
-        NOTICE: Browser URL= http://localhost:1234
-    (hit Ctrl-C to break the execution)
-    info sharedlibrary afb-*
-```
-
-# Running an debugging on a target
-
-```bash
-export RSYNC_TARGET=root@xx.xx.xx.xx
-export RSYNC_PREFIX=/opt    # WARNING: installation directory should exist
-
-mkdir $RSYNC_TARGET
-cd    $RSYNC_TARGET
-
-cmake -DRSYNC_TARGET=$RSYNC_TARGET -DRSYNC_PREFIX=$RSYNC_PREFIX ..
-make remote-target-populate
-
-    ./build/target/start-${RSYNC_TARGET}.sh
-    firefox http://localhost:1234    # WARNING: do not forget firewall if any
-
-    ssh -tt ${RSYNC_TARGET} speaker-test -twav -D hw:ep01 -c 2
-```
-
-Note: remote-target-populate will
-
-* create a script to remotely start the binder on the target in ./build/target/start-on-target-name.sh
-* create a gdbinit file to transparently debug remotely in source code with gdb -x ./build/target/gdb-on-target-name.ini
-* to run and debug directly from your IDE just configure the run and debug properties with the corresponding filename
-* run a generic control and pass virtual channel as a parameter (check remaning PCM in plugin)
-
-Note that Netbeans impose to set debug directory to ./build/pkgout or it won't find binding symbols for source debugging

-## Handle dependencies using packager > (OpenSuse-42.2, Fedora-25, Ubuntu 16.04.2LTS)
-
-Using system package repositories:
-
-* gcc > 4.8
-* systemd-devel (libsystemd-dev>=222)
-* libuuid-devel (OpenSuse) or uuid-dev (Ubuntu)
-* file-devel(OpenSuSe) or libmagic-dev(Ubuntu)
-* libjson-c-devel
-* ElectricFence (BUG should not be mandatory)

-
-You might want to add following variables into ~/.bashrc:
-
-```bash
-    echo "#----------  AGL options Start ---------" >>~/.bashrc
-    echo "# Object: AGL cmake option for  binder/bindings" >>~/.bashrc
-    echo "# Date: `date`" >>~/.bashrc
-    echo 'export CC=gcc-5; export CXX=g++-5' >>~/.bashrc   # if using gcc5
-    echo 'export INSTALL_PREFIX=$HOME/opt' >>~/.bashrc
-    echo 'export LD_LIBRARY_PATH=$INSTALL_PREFIX/lib64:$INSTALL_PREFIX/lib' >>~/.bashrc
-    echo 'export LIBRARY_PATH=$INSTALL_PREFIX/lib64:$INSTALL_PREFIX/lib' >>~/.bashrc
-    echo 'export PKG_CONFIG_PATH=$INSTALL_PREFIX/lib64/pkgconfig:$INSTALL_PREFIX/lib/pkgconfig' >>~/.bashrc

-
-## Handle dependencies from sources
-
-Install devel packages from your system official repositories and use the
-following instructions to install `libmicrohttpd` and `app-framework-binder`:
-
-```bash
-    # install LibMicroHttpd
-    LIB_MH_VERSION=0.9.55
-    wget https://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-${LIB_MH_VERSION}.tar.gz
-    tar -xzf libmicrohttpd-${LIB_MH_VERSION}.tar.gz
-    cd libmicrohttpd-${LIB_MH_VERSION}
-    ./configure --prefix=${INSTALL_PREFIX}
-    make
-    sudo make install-strip
-
-    # retrieve last AFB_daemon from AGL
-    git clone https://gerrit.automotivelinux.org/gerrit/src/app-framework-binder
-
-    # Warning: previous GCC options should be set before initial cmake (clean Build/*)
-    cd app-framework-binder; mkdir -p build; cd build
-    cmake -DCMAKE_INSTALL_PREFIX=$INSTALL_PREFIX ..
