[CMake] FindLAPACK problem

[Tim Gallagher]

I've found and fixed another problem.

When using Intel MKL, Pthreads is also required. There is a call to find_package for Threads in FindLAPACK, and when it checks that the libraries work in the macro, it links against them so the test build works fine. But at the end of the macro, when building the list of libraries used for lapack, it does not include threads as it should.

I've submitted another bug report and uploaded patches, again for both master and release. Ticket number is 12625.

My colleague, Andy Smith, found the problem. 

The CMAKE_FIND_LIBRARY_SUFFIXES variable was mispelled as CMAKE_FIND_LIBRRAY_SUFFIXES causing errors. 

I created a ticket in Mantis and attached patches for both origin/master and origin/release. The ticket is number 12624.

Hi,

I sent this out awhile ago, saying it couldn't find the MKL LAPACK. But I think the problem may be bigger than that because it can't find non-MKL lapack for me either. I get:

-- A library with BLAS API found.
-- A library with BLAS API found.
CMake Error at /usr/share/cmake/Modules/FindLAPACK.cmake:295 (message):
  A required library with LAPACK API not found.  Please specify library
  location.

/usr/lib64/liblapack_pic.a  /usr/lib64/liblapack.so.3

So I have BLAS and LAPACK installed from OpenSuSE and CMake 2.8.6. This is sort of a show stopper if we can't get FindLAPACK working.
