Question

我有一个C ++应用程序，它取决于几个.dylib;其中包括libproj和PythonQt。

我在不同的目录中预先构建了这些库。

2（相关）问题：

可执行文件找到libproj.dylib的完整路径，虽然它不在路径中，不在DYLD_LIBRARY_PATH中，而不在QtCreator的配置中。怎么样？
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_LIBRARY_PATH中手动添加正确的路径。为什么？

这可能与libproj有.la和.dylib这一事实有关，但对于PythonQt只有.dylib;但我不确定，我不明白这种关系。

otool的示例输出：

/Users/arnaud/Projects/myprojectname/external/proj-4.8.0/bin_mac64_gcc421_release/lib/libproj.0.dylib (compatibility version 8.0.0, current version 8.0.0)
    ( so it finds libproj correctly, even in another directory )

libPythonQt.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    (... but not libPythonQt, which is in a similar directory )
