The FindBLAS works fine but most of the blas implementations are provided as an ar-archive somewhere in the filesystem ( we use a standard blas, ATLAS, GotoBlas or malefactor specific variants). Is it possible to pass the wanted libblas.a as a parameter to cmake and add it to a target?

FIND_PACKAGE(BLAS REQUIRED)

ADD_EXECUTABLE(output myfile.c)
TARGET_LINK_LIBRARIES(output ${BLAS_LIBRARIES})
