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)

You can use the qt_add_grpc CMake command to implicitly call Qt GRPC code generation for your project.

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.

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