在不使用'make install‘的情况下在cmake中添加符号链接

Question

我有一大堆的库需要构建。我为每个库创建了3个sym-link。我使用以下命令创建了两个符号链接：

add_library(${PROJECT_NAME} ${SRC})
set_target_properties(${PROJECT_NAME} PROPERTIES SOVERSION ${perception_kit_VERSION})
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS} ${Boost_LIBS})

但剩下的两个是使用以下命令创建的：

#code for generating symlink. will work with make install
if (CMAKE_HOST_UNIX)
  set (libname_major_minor_patch "lib${PROJECT_NAME}.so.${perception_kit_VERSION_MAJOR}.${perception_kit_VERSION_MINOR}.${perception_kit_VERSION_PATCH}")
  set (libname_major_minor "lib${PROJECT_NAME}.so.${perception_kit_VERSION_MAJOR}.${perception_kit_VERSION_MINOR}")
  set (libname_major "lib${PROJECT_NAME}.so.${perception_kit_VERSION_MAJOR}")
  set (libname "lib${PROJECT_NAME}.so")

  install(CODE "
          EXECUTE_PROCESS (COMMAND ln -sf ${libname_major_minor_patch} ${libname_major_minor}  WORKING_DIRECTORY ${LIBRARY_OUTPUT_PATH} )
")
  install(CODE "
          EXECUTE_PROCESS (COMMAND ln -sf ${libname_major_minor_patch} ${libname_major}  WORKING_DIRECTORY ${LIBRARY_OUTPUT_PATH} )
")

endif(CMAKE_HOST_UNIX)

后两个仅在使用make install时创建。有没有办法在不使用make install的情况下创建所有sym链接。？

Answer 1

要执行生成后命令，可以使用add_custom_command(TARGET ...)

所以在这种情况下，我猜你会想要这样的东西

add_custom_command(
    TARGET ${PROJECT_NAME} POST_BUILD
    COMMAND ln -sf ${libname_major_minor_patch} ${libname_major_minor}
    COMMAND ln -sf ${libname_major_minor_patch} ${libname_major}
)
