从CMAKE调用MIDL编译器

Question

我将在CMAKE中使用MIDL编译器，但无法从CmakeList调用MIDL编译器

这就是我用来达到目标的命令。

add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/IFace.h ${CMAKE_CURRENT_BINARY_DIR}/GUIDS.c ${CMAKE_CURRENT_BINARY_DIR}/Proxy.c ${CMAKE_CURRENT_BINARY_DIR}/ProxyDll.c
COMMAND midl /h IFace.h /iid GUIDS.c /proxy Proxy.c /dlldata ProxyDll.c ${CMAKE_CURRENT_LIST_DIR}/include/Server.idl
)

当我构建我的项目时，${CMAKE_CURRENT_BINARY_DIR}中没有由MIDL编译器生成的文件

但是有了这个签名文件，就能很好地生成

add_custom_command(
PRE_BUILD
TARGET ${PROJECT_NAME}
COMMAND midl /h IFace.h /iid GUIDS.c /proxy Proxy.c /dlldata ProxyDll.c ${CMAKE_CURRENT_LIST_DIR}/include/Server.idl
)

我做错了什么？

Answer 1

这就是它的工作方式：

set(MIDL_OUTPUT
    ${CMAKE_CURRENT_BINARY_DIR}/IFace.h
    ${CMAKE_CURRENT_BINARY_DIR}/GUIDS.c
    ${CMAKE_CURRENT_BINARY_DIR}/Proxy.c
    ${CMAKE_CURRENT_BINARY_DIR}/ProxyDll.c
    )
set(MIDL_FILE
    ${CMAKE_CURRENT_LIST_DIR}/include/Server.idl
    )
add_custom_command(
    OUTPUT ${MIDL_OUTPUT}
    COMMAND midl /h IFace.h /iid GUIDS.c /proxy Proxy.c /dlldata ProxyDll.c ${MIDL_FILE}
    WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
    DEPENDS ${MIDL_FILE}
    VERBATIM
    )
add_custom_target(midl-cmplr
    DEPENDS ${MIDL_OUTPUT}
    )
add_dependencies(${PROJECT_NAME}
    midl-cmplr
    )
set_source_files_properties(
    ${MIDL_OUTPUT}
        PROPERTIES
            GENERATED TRUE
            )

Answer 2

为了改进@definename的回答和@nathan的评论，只要将输出添加到源文件列表中，就没有必要执行add_custom_target，因此修改后的答案如下：

set(MIDL_OUTPUT
    ${CMAKE_CURRENT_BINARY_DIR}/IFace.h
    ${CMAKE_CURRENT_BINARY_DIR}/GUIDS.c
    ${CMAKE_CURRENT_BINARY_DIR}/Proxy.c
    ${CMAKE_CURRENT_BINARY_DIR}/ProxyDll.c
)
set(MIDL_FILE
    ${CMAKE_CURRENT_LIST_DIR}/BookSku.idl
)
add_custom_command(
    OUTPUT ${MIDL_OUTPUT}
    COMMAND midl /h IFace.h /iid GUIDS.c /proxy Proxy.c /dlldata ProxyDll.c ${MIDL_FILE}
    WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
    DEPENDS ${MIDL_FILE}
    MAIN_DEPENDENCY ${MIDL_FILE}
    VERBATIM
)
# add_custom_target(midl-cmplr
#     DEPENDS ${MIDL_OUTPUT}
# )
# add_dependencies(${PROJECT_NAME}
#     midl-cmplr
# )
# set_source_files_properties(${MIDL_OUTPUT} PROPERTIES
#   GENERATED TRUE
# )
target_sources(${PROJECT_NAME} PRIVATE ${MIDL_FILE} ${MIDL_OUTPUT})
