- export library path for gmp/mpfr from CGAL config files.
This is required when non-system gmp/mpfr libraries are being
used, but not using a ThirdParty compiler installation.
- automatically handle lib/ vs lib64/ (eg, for central installations)
for packages such as boost, CGAL, etc. While the ThirdParty
compilation of these will normally land in lib64/, this may not be
the case when they are supplied by another means.
- reworked the handling of foamEtcFile and foamCleanPath for less
clutter in the configuration files.
Added the bin/tools/lib-dir script to handle logic that is
too complex to easily manage in csh.
etc/config.sh and etc/config.csh
This structure is more convenient to add support for other shells, e.g. zsh, fish etc.
Resolves feature request to simplify support for other shells in
