Newer CGAL versions build into lib64, breaking current CGAL make rules.
On 64-bit systems, the system installations of boost, cgal are under
The behaviour for a ThirdParty build is mostly
lib/ but this can also be changing.
- Boost 1_62_0 and older build into 'lib/'.
- CGAL-4.9 builds into 'lib64/', older versions into 'lib/'.
Future-proof things by using
lib$WM_COMPILER_LIB_ARCH for boost and cgal build rules, and forcing these as build targets in the ThirdParty makeCGAL as well.
