# CMake Commands in Qt6 GRPC

You should call the following CMake commands to use the Qt6::Grpc module in your project:

     find_package(Qt6 REQUIRED COMPONENTS Grpc)

     target_link_libraries(mytarget PRIVATE Qt6::Grpc)

To generate gRPC services using Qt GRPC and link them with your program consider the following example:

     cmake_minimum_required(VERSION 3.16...3.22)
     project(MyProject)

     find_package(Qt6 REQUIRED COMPONENTS Protobuf Grpc)
     qt_standard_project_setup()

     qt_add_protobuf(MyProtoMessageLib
         PROTO_FILES
             path/to/helloworld.proto
         PROTO_INCLUDES
             path/to/proto/include
     )

     qt_add_grpc(MyGrpcClient CLIENT
         PROTO_FILES
             path/to/helloworld.proto
         PROTO_INCLUDES
             path/to/proto/include
     )

     qt_add_executable(MyApp main.cpp)

     target_link_libraries(MyApp PRIVATE MyGrpcClient MyProtoMessageLib Qt6::Protobuf)

The example above calls the `qt_add_grpc()` CMake function to generate a library called `MyGrpcClient`.

Note: if the `.proto` file API contains messages, then the `qt_add_protobuf()` CMake function should be called to generate protobuf message classes for the project.

Finally, the example creates a target for an executable called MyApp which links to the MyGrpcClient and MyProtoMessageLib libraries.
