qt_add_grpc
Generates Qt-based C++ services using a protobuf schema
Note: This command is in technology preview and may change in future releases.
This command was introduced in Qt 6.5.
Usually qtgrpcgen is invoked through the qt_add_grpc CMake macro.

)
The source files are created by qtgrpcgen and added to the target. If the target already exists, the files are added to the target source list. If the target doesn't exist, it is created as a library which you must link to.
Arguments
TARGET_TYPEis the type of gRPC code to be generated. Since gRPC supports a client-server architecture,CLIENTorSERVERsource code may be generated.Note: for Qt 6.5 only
CLIENTsource code generation is supported.COPY_COMMENTScopies comments from.protofiles. If provided in the parameter list, comments related to messages and fields are copied to generated header files.GENERATE_PACKAGE_SUBFOLDERSgenerates a folder structure for the generated files matching the.protofile's package name. For example,package io.qt.test;would put the generated files intoio/qt/test/.EXTRA_NAMESPACEis an optional namespace that will be used for the generated classes. The classes are always generated in a namespace whose name is the same as the package name specified in the.protofile. If this option is used, then everything will be nested inside the extra namespace.EXPORT_MACROis the base name of the symbol export macro used for the generated code. The generated macro name is constructed asQPB_<EXPORT_MACRO>_EXPORT. If the option is not set, the macro is not generated.PROTO_FILESis the list of.protofiles that will be used in the generation procedure.PROTO_INCLUDESis the list of directories that will be searched for dependencies.OUTPUT_DIRECTORYis the directory where the generated files will be put. By default, the current directory (while evaluating the function) is used.OUTPUT_HEADERScan be used to specify a variable that will hold the list of headers created by the function. This list can be useful for custom project install rules.OUTPUT_TARGETScan be used to specify a variable that will hold the list of targets created by the function. This list can be useful for custom project install rules.
