When there are multiple proto file inputs, they are matched with the provided proto directories (-I option). These directories are tested sequentially for each input proto file and if input file is in a subdirectory of provided proto directories, this directory is considered as base for calculating output directory. This update provides same manner and removes limitations imposed by using `${CMAKE_CURRENT_SOURCE_DIR}` as main proto import directory.
1- `${CMAKE_CURRENT_SOURCE_DIR}` is only added to include directories if no import directory is provided and we are not in `APPEND_PATH` mode. In addition it is added as last possible directory to decrease its priority in searching.
2- Each directory is checked against `${_protobuf_include_path}` to find first possible directory which is parent directory of input proto file. If a directory is found, `${_rel_dir}` is calculated based on its value. If no suitable folder is found, an error will be generated.
This reverts commit 93f6b67eb2.
Protoc adds already the relative path to the output directory.
Therefore, we have to remove this again from the output directory
to prevent adding it twice.
Without this fix, protobuf_generate() sets the variable _generated_srcs to
${protobuf_generate_PROTOC_OUT_DIR}/${_rel_dir}/${_basename}${_ext}
but generates the files in
${protobuf_generate_PROTOC_OUT_DIR}/${_basename}${_ext}
A series of improvements:
- Improved Protobuf module compatibility (disabled by default);
- Hide advanced settings;
- Added build tree configuration;
- Added build of examples.
