After tests were bundled in a single executable and cycles and libmv created their own tests, the warnings on macOS have gone over 800. The reason is setting `*_LIBRARIES` to names of the libraries and later using `link_directories` to link them properly. https://cmake.org/cmake/help/latest/command/link_directories.html > Note This command is rarely necessary and should be avoided where > there are other choices. Prefer to pass full absolute paths to > libraries where possible, since this ensures the correct library > will always be linked. The find_library() command provides the > full path, which can generally be used directly in calls to > target_link_libraries(). Warnings like the following popup for every target/executable, for every library it links to. ``` ld: warning: directory not found for option '-L/Users/me/blender-build/blender/../lib/darwin/jpeg/lib/Debug' ``` The patch completes a step towards removing `link_directories` as mentioned in TODO at several places. The patch uses absolute paths to link libraries and removes all `*_LIBPATH`s except `PYTHON_LIBPATH` from `platform_apple.cmake` file. (The corner case where it's used seems like dead code. Python is no longer shipped with that file structure.) Also, unused code for LLVM-3.4 has been removed. Also, guards to avoid searching libraries in system directories have been added. `APPLE` platform now no longer needs `setup_libdirs`, `cycles_link_directories`, and `link_directories`. The number of warnings now is less than 100, most of them being deprecation ones in dependencies. This patch depended on {rBb746179d0add}, {rB2fdbe4d05011}, {rB402a4cadba49} and {rBd7f482f88ecb}.
