我一直在收集一个 CMakeLists.txt 来编译现在是一个 SFML 示例，以准备编写我自己的源代码。感觉就像一个 hack，即使它现在可以工作(Mac Makefile、VS nmake、VS 解决方案)。

主存储库位于 https://github.com/iaefai/Spider-Fish/

欢迎提出任何建议。

最大的 hack 似乎是复制资源的东西。如果有一个可以在多平台上执行此操作的特殊命令，那将是理想的选择。不完全确定该怎么做——我怀疑 set_target_resources 是个好名字。

IF (APPLE)

    set_target_properties(${PROJECT_NAME} 
        PROPERTIES
            MACOSX_BUNDLE_INFO_PLIST ${CMAKE_CURRENT_SOURCE_DIR}/src/mac/Spider-Fish-Info.plist
            MACOSX_BUNDLE  TRUE)      

#    add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
    add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD 
        COMMAND echo copying resources... 
        #${RESOURCES}
        COMMAND mkdir -p ./${PROJECT_NAME}.app/Contents/Resources
        COMMAND cp ${RESOURCES} ./${PROJECT_NAME}.app/Contents/Resources                
    )
#    add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND echo ${PROJECT_NAME}.app/Contents/Resources)


ENDIF (APPLE)

IF (WIN32)
    set_target_properties(${PROJECT_NAME}
        PROPERTIES
            WIN32_EXECUTABLE FALSE)

我会担心 Windows 上的这些自定义内容，因为它变得非常专业。

    set(EXTRA_LIBS sfml-main ${OPENGL_LIBRARIES})
    # note we can add stuff to ADDITIONAL_MAKE_CLEAN_FILES 
    string(COMPARE EQUAL ${CMAKE_GENERATOR} "NMake Makefiles" NMAKE)
    if (NMAKE)
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
            COMMAND echo copying dlls...
            COMMAND copy ${SFML_INCLUDE_DIR}\\..\\bin\\*.dll .
            COMMAND echo copying resources... from ${CMAKE_CURRENT_SOURCE_DIR}
            COMMAND -mkdir resources 
            COMMAND copy \"${CMAKE_CURRENT_SOURCE_DIR}\\assets\\*.*\" resources)
    else ()
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
            COMMAND echo copying dlls...
            COMMAND copy ${SFML_INCLUDE_DIR}\\..\\bin\\*.dll .
            COMMAND echo copying resources... from ${CMAKE_CURRENT_SOURCE_DIR}
            # Visual Studio does not support the '-' to ignore errors
            COMMAND rmdir /s /q resources
            COMMAND mkdir resources 
            COMMAND copy \"${CMAKE_CURRENT_SOURCE_DIR}\\assets\\*.*\" resources)
    endif (NMAKE)
ENDIF (WIN32)

#if (APPLE)
target_link_libraries(${PROJECT_NAME} 
    sfml-system 
    sfml-window
    sfml-network
    sfml-graphics
    sfml-audio
    ${EXTRA_LIBS})
#endif (APPLE)

最佳答案

您是否尝试过使用 INSTALL 命令而不是自定义的后期构建步骤。
