FindProtobuf
Locate and configure the Google Protocol Buffers 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.
- PROTOBUF_IMPORT_DIRS
- List of additional directories to be searched for
imported .proto files.
Defines the following variables:
- PROTOBUF_FOUND
- Found the Google Protocol Buffers library
(libprotobuf & header files)
- PROTOBUF_INCLUDE_DIRS
- Include directories for Google Protocol Buffers
- PROTOBUF_LIBRARIES
- The protobuf libraries
- PROTOBUF_PROTOC_LIBRARIES
- The protoc libraries
- PROTOBUF_LITE_LIBRARIES
- The protobuf-lite libraries
The following cache variables are also available to set or use:
- PROTOBUF_LIBRARY
- The protobuf library
- PROTOBUF_PROTOC_LIBRARY
- The protoc library
- PROTOBUF_INCLUDE_DIR
- The include directory for protocol buffers
- PROTOBUF_PROTOC_EXECUTABLE
- The protoc compiler
- PROTOBUF_LIBRARY_DEBUG
- The protobuf library (debug)
- PROTOBUF_PROTOC_LIBRARY_DEBUG
- The protoc library (debug)
- PROTOBUF_LITE_LIBRARY
- The protobuf lite library
- PROTOBUF_LITE_LIBRARY_DEBUG
- The protobuf lite library (debug)
Example:
find_package(Protobuf REQUIRED)
include_directories(${PROTOBUF_INCLUDE_DIRS})
include_directories(${CMAKE_CURRENT_BINARY_DIR})
protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS foo.proto)
add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
target_link_libraries(bar ${PROTOBUF_LIBRARIES})
Note
The PROTOBUF_GENERATE_CPP macro and add_executable() or
add_library() calls only work properly within the same
directory.

protobuf_generate_cpp
Add custom commands to process .proto files:
protobuf_generate_cpp (<SRCS> <HDRS> [<ARGN>...])
- SRCS
- Variable to define with autogenerated source files
- HDRS
- Variable to define with autogenerated header files
- ARGN
- .proto files
