+# This is an example script for use with CMake projects for locating and configuring
+# the nanopb library.
+#
+# 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:
+# PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler
+# NANOPB_GENERATOR_SOURCE_DIR - The nanopb generator source
+#
+# ====================================================================
+#
+# 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} ${NANOPB_SRC_ROOT_FOLDER}/cmake)
+# find_package( Nanopb REQUIRED )
+# include_directories(${NANOPB_INCLUDE_DIRS})
+#
+# NANOPB_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
+#
+# include_directories(${CMAKE_CURRENT_BINARY_DIR})
+# add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
