System Information
Operating system: MacOS Catalina (10.15.6)
Graphics card: N/A

Blender Version
Using master

Short description of error
When running configure using CMake (on MacOS) with the precompiled libs in a custom location, I would like to tell CMake where to find the libs, which seems to be possible using LIBDIR; however, this is ignored.

On inspecting code, it seems that the CMAKE_PREFIX_PATH is only set for the built-in libdir. If this is set for the custom libdir passed in with LIBDIR, the configure step completes successfully.

Exact steps for others to reproduce the error
In build directory, run cmake -DLIBDIR=/path/to/precompiled/libs/lib/darwin /path/to/blender/source
Note that message "Using pre-compiled LIBDIR: /path/to/precompiled/libs/lib/darwin" appears, but then "Could NOT find ALEMBIC", "Could NOT find USD", etc, which eventually causes the configure step to fail.
