目标包时未设置 qt 的 CMake DragNDrop 框架 rpath

Question

当使用 brew qt5.13.0 提供的 qt 框架为我的项目创建 DragNDrop 包时，尽管我将其设置为将框架复制到我的包中的路径，但 rpath 似乎并没有被接受。

我已经尝试了 set(MACOSX_RPATH ON) 和 set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE) 但结果仍然使用静态路径而不是 rpath 并且无法在其他机器上找到捆绑的框架 brew qt 5.13.0

在 5.9.5 中，我的 cmake 按预期工作所需的全部是 set (CMAKE_INSTALL_RPATH "@executable_path/../Frameworks") 再往下进行包装

        set (CPACK_GENERATOR "DragNDrop")
        install (DIRECTORY ${Qt5_DIR}/../../QtCore.framework DESTINATION *.app/Contents/Frameworks)
        install (DIRECTORY ${Qt5_DIR}/../../QtGui.framework DESTINATION *.app/Contents/Frameworks)
        install (DIRECTORY ${Qt5_DIR}/../../QtPrintSupport.framework DESTINATION *.app/Contents/Frameworks)
        install (DIRECTORY ${Qt5_DIR}/../../QtTest.framework DESTINATION *.app/Contents/Frameworks)
        install (DIRECTORY ${Qt5_DIR}/../../QtWidgets.framework DESTINATION *.app/Contents/Frameworks)
        install (FILES "${Qt5_DIR}/../../../plugins/platforms/libqcocoa.dylib" DESTINATION *.app/Contents/PlugIns/platforms)

在开源安装程序的 qt 5.9.5 上，我使用 otool -L 看到以下结果

    /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 1570.15.0)
    /System/Library/Frameworks/OpenCL.framework/Versions/A/OpenCL (compatibility version 1.0.0, current version 1.0.0)

    /usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)

而当使用 brew 的 qt 5.13.0 时，我得到以下结果

    /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 1575.17.0)
    /System/Library/Frameworks/OpenCL.framework/Versions/A/OpenCL (compatibility version 1.0.0, current version 1.0.0)

    /usr/local/opt/qt/lib/QtGui.framework/Versions/5/QtGui (compatibility version 5.13.0, current version 5.13.0)
    /usr/local/opt/qt/lib/QtCore.framework/Versions/5/QtCore (compatibility version 5.13.0, current version 5.13.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.4)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.250.1)

经过大量挖掘，我终于弄清楚发生了什么。正如 benlau here when brew builds qt they use the -no-rpath option. So rather than go through and use install_name_tool on the frameworks I needed I discovered a neat trick about the qt-online-installer. It was script-able and I found a repo with that in it, see qtci 所见。

然后添加后

        - git clone https://github.com/benlau/qtci.git; 
        - source qtci/path.env; 
        - install-qt-online qt.qt5.5130.clang_64 ~/

到 -travis.yml 我可以用预期的 rpaths

设置我的 Qt_DIR="~/qt/5.13.0/clang_64/lib/cmake/Qt5" 和 link

    /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 1575.17.0)
    /System/Library/Frameworks/OpenCL.framework/Versions/A/OpenCL (compatibility version 1.0.0, current version 1.0.0)
    @rpath/QtWidgets.framework/Versions/5/QtWidgets (compatibility version 5.13.0, current version 5.13.0)
    @rpath/QtGui.framework/Versions/5/QtGui (compatibility version 5.13.0, current version 5.13.0)
    @rpath/QtCore.framework/Versions/5/QtCore (compatibility version 5.13.0, current version 5.13.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.4)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.250.1)
    /usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)
