+# This is an example script for use with CMake projects for locating and configuring
+# the nanopb library.
+#
+# The following varialbes have to be set:
+#
+#   NANOPB_SRC_ROOT_FOLDER  - Path to nanopb source folder
+#
+# The following variables can be set and are optional:
+#
+#
+#   PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set
+#                              the protobuf-default VS project build locations
+#                              (vsprojects/Debug & vsprojects/Release) will be searched
+#                              for libraries and binaries.
+#
+#   NANOPB_IMPORT_DIRS       - List of additional directories to be searched for
+#                              imported .proto files.
+#
+#   NANOPB_GENERATE_CPP_APPEND_PATH - By default -I will be passed to protoc
+#                                     for each directory where a proto file is referenced.
+#                                     Set to FALSE if you want to disable this behaviour.
+#
+# Defines the following variables:
+#
+#   NANOPB_FOUND - Found the nanopb library (source&header files, generator tool, protoc compiler tool)
+#   NANOPB_INCLUDE_DIRS - Include directories for Google Protocol Buffers
+#
+# The following cache variables are also available to set or use:
+#   NANOPB_GENERATOR_EXECUTABLE - The nanopb generator
+#   PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler
+#
+#  ====================================================================
+#
+# NANOPB_GENERATE_CPP (public function)
+#   SRCS = Variable to define with autogenerated
+#          source files
+#   HDRS = Variable to define with autogenerated
+#          header files
+#   ARGN = proto files
+#
+#  ====================================================================
+#  Example:
+#
+#   set(NANOPB_SRC_ROOT_FOLDER "/path/to/nanopb")
+#   set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${NANOPB_SRC_ROOT_FOLDER}/cmake)

+#   include_directories(${NANOPB_INCLUDE_DIRS})
+#
+#   NANOPB_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
