在编译时更新资源

  • 772

我有一个应该集成 tlb 的 COM 服务器。我使用 cmake (ToolChain Visual Studio 2019) 和以下命令收集它

set(SOURCES ... myLib.idl myLib.rc)
add_executable(myLib.exe WIN32 ${SOURCES})

set(MIDL_OUTPUT
    ${CMAKE_CURRENT_LIST_DIR}/myLib_i.h
    ${CMAKE_CURRENT_LIST_DIR}/myLib_i.c
)

set(MIDL_FILE ${CMAKE_CURRENT_LIST_DIR}/myLib.idl)

set(TLB_NAME "${CMAKE_CURRENT_LIST_DIR}/myLib.tlb")
add_custom_command(
        OUTPUT ${MIDL_OUTPUT}
        COMMENT "midl /h myLib_i.h /iid myLib_i.c /tlb ${TLB_NAME} /proxy myLib_p.c ${MIDL_FILE} /env x64 /W1 /char signed /robust /nologo /Oicf /target NT60"
        COMMAND midl /h myLib_i.h /iid myLib_i.c /tlb ${TLB_NAME} /proxy myLib_p.c ${MIDL_FILE} /env x64 /W1 /char signed /robust /nologo /Oicf /target "NT60"
        WORKING_DIRECTORY ${CMAKE_CURRENT_LIST_DIR}
        DEPENDS ${MIDL_FILE}
        MAIN_DEPENDENCY ${MIDL_FILE}
        VERBATIM
)
target_sources(myLib.exe PRIVATE ${MIDL_FILE} ${MIDL_OUTPUT})

并myLib.rc归档

1 TYPELIB "myLib.tlb"

问题：修改idl文件后，将上一版本的tlb文件添加为资源。直到我对项目进行一般构建

据我了解，问题在于编译不会更新myLib.rc.res. 如何强制它更新？

    结果是这样的：

    add_custom_command(
    OUTPUT ${MIDL_OUTPUT}
    COMMENT "midl /h myLib_i.h /iid myLib_i.c /tlb ${TLB_NAME} /proxy myLib_p.c ${MIDL_FILE} /env x64 /W1 /char signed /robust /nologo /Oicf /target NT60"
    COMMAND midl /h myLib_i.h /iid myLib_i.c /tlb ${TLB_NAME} /proxy myLib_p.c ${MIDL_FILE} /env x64 /W1 /char signed /robust /nologo /Oicf /target "NT60"
    COMMAND "C:/Program Files/Git/usr/bin/touch.exe" -c "-r${TLB_NAME}" "${CMAKE_CURRENT_LIST_DIR}/myLib.rc"
    WORKING_DIRECTORY ${CMAKE_CURRENT_LIST_DIR}
    DEPENDS ${MIDL_FILE}
    MAIN_DEPENDENCY ${MIDL_FILE}
    VERBATIM
)

    我add_custom_command又添加了一个命令，该命令在创建 tlb 时会更改 rc 文件的创建日期。之后，编译器本身重新编译myLib.rc.res
