# QtProtobuf

Protobuf plugin to generate Qt classes

## Linux Build
### Prerequesties
Check installation of protobuf and grpc in your system. Minimum required versions are protobuf-3.6.0 and grpc-1.15.0.

**Note:** Older versions could be supported as well but not officially tested.

#### All-in-one build
If required versions of libraries are not found in your system, you may use all-in-one build procedure for prerequesties

Clone grpc project from official repository to 3rdparty folder:

```bash
git submodule update --init --recursive
```
### Build
```bash
mkdir build
cd build
cmake ..
cmake --build . -j <N> [--config <RELEASE|DEBUG>]
```
