[CMake] Bug in cmake 2.8.11 when detecting sgemm function from MKL 11.0

[Bogdan Cristea]

Hi

Attached you shall find the test file (note that you need to install MKL
11.0). I have used Windows 8 x86_64 and Visual Studio 2010 x86. The problem
seems to be in the way the variable CMAKE_REQUIRED_LIBRARIES is parsed. The
commented line represents a different error case. With cmake v2.8.10 I
don't get any error.

regards
Bogdan
