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_executable(MyApp main.cpp)

qt_add_protobuf(MyApp
    PROTO_FILES
        path/to/messages.proto
)

qt_add_grpc(MyApp CLIENT
    PROTO_FILES
        path/to/service.proto
)

target_link_libraries(MyApp PRIVATE Qt6::Protobuf Qt6::Grpc)

The example above calls the qt_add_grpc() CMake function to start Qt GRPC code generation for service sections within the provided protobuf schema.

Since we reuse the executable target, all generated files will be appended to the target, and the include directories will be updated accordingly.
