@cad/occt: import Open CASCADE Technology

Development platform providing services for 3D surface and solid modeling, CAD
data exchange, and visualization. Most of OCCT functionality is available in
the form of C++ libraries. OCCT can be best applied in development of software
dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical
simulation (CAE).

@$NetBSD$

From cad/oce:
Define SIGFPE macros on SunOS.
Avoid overlapping reference in case statements.
Respect the reality as CMake found it, there might not be libsunmath.
