Summary

0013528: FindBLAS does not find MKL 10.3 when using gcc 4.x

Description

This report closely relates to 0013394. After applying in CMake 2.8.9 the fix proposed there, FindBLAS cannot locate MKL 10.3. The reason for this is that gomp was added to the searched list of libraries searched by Check_Fortran_Libraries. However gomp is not in the list of patch searched by find_library by default, which makes the search fail.

The proposed solution is to revert the FinbBLAS back to the 2.8.8 and patch FindLAPACK instead to resolve 0013394. In the attachment I enclose the proposed patch against 2.8.9.
