@loader_path missing from LC_RPATH on macos #142

On macos it seems that @loader_path is missing from the LC_RPATH of the dynamic library which means that it cannot load the dll's of other plugins it depends on.

This is not the case for all plugins (libDataPropertiesPlugin, libPointData, etc...)

As a workaround you can add @loader_path to the dylib by using "install_name_tool -add_rpath @loader_path .
