我花了一周时间试图获得一些我在Linux上工作的东西来使用OSX,但无济于事。我已经尝试阅读关于rpath的CMake文章以及关于它的各种其他SO帖子以及与我的CMakeLists.txt进行混淆以使其工作,但我已经失败了,我希望有人可以在这里给我一些关于我做错的提示。

install(TARGETS ${EXECUTABLE_NAME} DESTINATION ${PROJECT_SOURCE_DIR}/bin)

当我用otool检查时,生成的可执行文件给了我:

Load command 41
          cmd LC_RPATH
      cmdsize 72
         path /Applications/Autodesk/maya2016/Maya.app/Contents/MacOS (offset 12)

哪个是正确的,但库路径是:

../bin/maya_standalone_test:
    @executable_path/libOpenMaya.dylib (compatibility version 0.0.0, current version 0.0.0)
    @executable_path/libOpenMayaAnim.dylib (compatibility version 0.0.0, current version 0.0.0)

    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

当然,当我运行应用程序时,我会得到:

dyld: Library not loaded: @executable_path/libOpenMaya.dylib
  Referenced from: /Users/sonictk/Git/experiments/maya_standalone_app_example/build/../bin/maya_standalone_test
  Reason: image not found
[1]    16909 trace trap  ../bin/maya_standalone_test

我尝试使用post build命令将@executable_path更改为@rpath而不是每个库,但是当找到库时,我遇到了可执行文件无法找到框架的问题(位于{{ 1}})以及链接到同一文件夹中其他动态库的其他问题(例如Maya' QtCore等)

当然,如果我将${MAYA_LOCATION}/Maya.app/Contents/Frameworks文件夹复制到我的可执行文件的父目录,将Frameworks/中的所有文件复制到与可执行文件相同的文件夹中,或者如果我设置{ {1}}和${MAYA_LIBRARY_DIR}在启动可执行文件之前指向库和框架指南。但我希望OSX上的这些库和框架能够动态链接,而不必像在Linux上那样修改环境。

我在这里做错了什么?
