如何用CMAKE在OSX包中包含库

Question

    dyld: Library not loaded: libxl.dylib
    Referenced from: 
    /path/to/executable/
      Reason: image not found

如果任何人有一个解决办法，或者可以指出我应该读什么的方向，以进一步理解这一点，这将是非常感谢的。

参见下面的cmakelists.txt

    cmake_minimum_required(VERSION 3.7)
    project(project name)

    set(CMAKE_CXX_STANDARD 14)

    set(SOURCE_FILES main.cpp)

    find_package( Qt5Core REQUIRED )
    find_package( Qt5Widgets REQUIRED )
    find_package( Qt5Gui REQUIRED )

    set(PROJECT_LINK_LIBS libxl.dylib)
    link_directories(${CMAKE_SOURCE_DIR}/LibXL/lib)
    include_directories(${CMAKE_SOURCE_DIR}/LibXL/include_cpp)


    #Mac Bundle (Built on Mac)
    add_executable(project_target_mac MACOSX_BUNDLE main.cpp)
    qt5_use_modules( project_target_mac Core Widgets Gui )
    target_link_libraries(project_target_mac Qt5::Widgets)
    target_link_libraries(project_target_mac ${PROJECT_LINK_LIBS} )
    #set_target_properties(project_target_mac PROPERTIES INSTALL_RPATH "${CMAKE_SOURCE_DIR}/LibXL/lib")

    add_executable(project_target ${SOURCE_FILES})
    qt5_use_modules( project_target Core Widgets Gui )
    target_link_libraries(project_target Qt5::Widgets)
    target_link_libraries(project_target ${PROJECT_LINK_LIBS

} )

在OSX上，人通常使用框架，并将其与安装规则集成到应用程序包中。

规则看起来像：

    install( DIRECTORY "${CMAKE_CURRENT_LIST_DIR}/ofxSyphon/libs/Syphon/lib/osx/Syphon.framework"
    DESTINATION ${APP_NAME}.app/Contents/Frameworks")

然后framework文件夹将被复制到应用程序包的contents/frameworks子文件夹中。为了使其发挥作用，应用程序本身应该安装如下内容：

install(TARGETS ${APP_NAME} DESTINATION .)
