libCGAL not found on OSX

[cedelmaier]

I'm attempting to install MemSurfer via the online instructions, and wound up with a problem when I attempt to actually run the installation script. I installed CGAL via homebrew, however, this is a header-only library, and so when I try to setup MemSurfer I get the following error:

  > MemSurfer = (/Users/cedelmaier/Projects/Biophysics/MemSurfer)
  > CGAL_ROOT = (/usr/local/Cellar/cgal/5.4/)
  > EIGEN_ROOT = (/usr/local/Cellar/eigen/3.4.0_1/)
  > BOOST_ROOT = (/usr/local/Cellar/boost/1.78.0_1/)
Traceback (most recent call last):
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 160, in <module>
    PATHS = fetch_paths(os.path.join(PATH_MEM, 'external'))
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 106, in fetch_paths
    paths['cgal'].update({'lib': find_shlib_path(paths['cgal']['root'], 'libCGAL')})
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 63, in find_shlib_path
    raise Exception(f'Find_shlib_path({path},{libname}) failed!')
Exception: Find_shlib_path(/usr/local/Cellar/cgal/5.4/,libCGAL) failed!

So really, need to know if the library is really needed, or change the installation instructions for the brew installation version to accommodate the different installation types.
