* This PR allows for extra exceptions in the debug mode (GCC/LLVM) on Linux based OSes - it does not work on the other operating systems.

* Added unit test for issue #521
Unit test adapted from https://github.com/qnzhou/libigl-unit-tests/blob/master/include/igl/delaunay_triangulation.cpp
* Fix iterator out of range error in lexicographic_triangulation (closes#521)
The iterator is now always decreased, so it points to the current left
side of the triangulation again after erasing the current item.
When the iterator is at the beginning of the boundary, it needs to point
to the last element (boundary.end()-1) after decreasing, so we have to
decrease the iterator in all cases.
In addition, the line
if (itr == left_itr || itr == right_itr) continue;
is simplified to
if (itr == left_itr) continue;
because the condition itr == right_itr will never be hit, because the
line before breaks the loop, when itr == right_itr:
if (itr == right_itr) break;
- Fixes#1229 by defaulting to static MSVC runtime on Windows.
- CMake will now fail if LIBIGL_WITH_CGAL is ON but CGAL is not found
(e.g. missing Boost or gmp/mpfr).
- Removed some duplicated template instantiations on Windows.
- Added IGL_DEBUG_OFF to disable slow unit test in Debug configuration
by default.
- Do not FORCE options given to third-party libraries.
