Correcting import path selection for protoc
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.Copyright 2008 Google Inc.

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site.
This README file contains protobuf installation instructions. To install protobuf, you need to install the protocol compiler (used to compile .proto files) and the protobuf runtime for your chosen programming language.
The protocol compiler is written in C++. If you are using C++, please follow the C++ Installation Instructions to install protoc along with the C++ runtime.
For non-C++ users, the simplest way to install the protocol compiler is to download a pre-built binary from our release page:
https://github.com/protocolbuffers/protobuf/releases
In the downloads section of each release, you can find pre-built binaries in zip packages: protoc-$VERSION-$PLATFORM.zip. It contains the protoc binary as well as a set of standard .proto files distributed along with protobuf.
If you are looking for an old version that is not available in the release page, check out the maven repo here:
https://repo1.maven.org/maven2/com/google/protobuf/protoc/
These pre-built binaries are only provided for released versions. If you want to use the github master version at HEAD, or you need to modify protobuf code, or you are using C++, it's recommended to build your own protoc binary from source.
If you would like to build protoc binary from source, see the C++ Installation Instructions.
Protobuf supports several different programming languages. For each programming language, you can find instructions in the corresponding source directory about how to install protobuf runtime for that specific language:
| Language | Source | Ubuntu | MacOS | Windows |
|---|---|---|---|---|
| C++ (include C++ runtime and protoc) | src |    |   | |
| Java | java |     | ||
| Python | python |               |    |  |
| Objective-C | objectivec |     | ||
| C# | csharp |  |  | |
| JavaScript | js |  |  | |
| Ruby | ruby |      |      | |
| Go | golang/protobuf | |||
| PHP | php |   |   | |
| Dart | dart-lang/protobuf |  |
The best way to learn how to use protobuf is to follow the tutorials in our developer guide:
