Revision: 69988 http://sourceforge.net/p/brlcad/code/69988 Author: starseeker Date: 2017-07-22 18:36:50 +0000 (Sat, 22 Jul 2017) Log Message: ----------- See if cotire (module for managing precompilation of headers) can help with our build times. Doesn't interact well with BRLCAD_ADDLIB, but openNURBS and step-g seem to be working.
