Update of /cvsroot/CMake/CMake/Modules
In directory public:/mounts/ram/cvs-serv28699/Modules
Added Files:
CheckFortranFunctionExists.cmake FindBLAS.cmake
FindLAPACK.cmake
Log Message:
ENH: FindBLAS.cmake and FindLAPACK.cmake modules added. They locate various implementations of blas and lapack libraries. CheckFortranFunctionExists.cmake provides a test function to check if the library is usabale. I have also changed the -KPIC flag to -fPIC in Linux-ifort.cmake.
