Comment(by robe):

 la is shown below.  I think I had to hand edit the lib path since its not
 referencable from within mingw configure and also was pointing in the
 wrong folder before.

 I did a dynamic build of SFCGAL, however, I think CGAL I did have to do
 some static compilation with Boost.

 Hard to follow (with my variable slots) but maybe this helps - my sfcgal
 build script:
