MacOS共享库路径 我有一个C++应用程序，它依赖于几个。其中，libproj和PythonQt

我在单独的目录中预先构建了这些lib

2（相关）问题：

• 可执行文件查找

  libproj.dylib

  的完整路径，尽管它不在路径中，不在

  DYLD\u LIBRARY\u路径中，也不在QtCreator的配置中。怎么做

• 可执行文件找不到PythonQt，尽管它的链接方式完全相同。我必须在

  DYLD\u LIBRARY\u path

  中手动添加正确的路径。为什么?

这可能与libproj有一个

.la

和一个

.dylib

有关，但PythonQt只有一个

.dylib

；但我不确定，我也不理解这种关系

    ( so it finds libproj correctly, even in another directory )
