问题
I am going to use MIDL compiler with CMAKE but unable to invoke MIDL compiler from CmakeList
That is command which I use to achieve my goal
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
)
When I build my project there are no files produced by MIDL compiler in ${CMAKE_CURRENT_BINARY_DIR}
But with this signature files generates well
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
)
What am I doing wrong?
回答1:
That is how it works:
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
)
回答2:
to improve upon @definename's answer and @nathan-moinvaziri's comment, it's not necessary to do add_custom_target
as long as you add the output to your source files list, so the revised answer is:
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})
