# 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} ${NANOPB_SRC_ROOT_FOLDER}/cmake)
# find_package( Nanopb REQUIRED )
# include_directories(${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})
