and handles the creation of different library lists whether the user wishes to link 15 # with a sequential BLAS or a multihreaded (BLAS_SEQ_LIBRARIES and BLAS_PAR_LIBRARIES). 16 # BLAS is detected with a FindBLAS call then if the BLAS vendor is Intel10_64lp, ACML 17 # or IBMESSLMT then the module attempts to find the corresponding multithreaded libraries. 18 # 19 # The following variables have been added to manage links with sequential or multithreaded 20 # versions: 21 # BLAS_INCLUDE_DIRS - BLAS include directories 22 # BLAS_LIBRARY_DIRS - Link directories for BLAS libraries 23 # BLAS_SEQ_LIBRARIES - BLAS component libraries to be linked (sequential) 24 # BLAS_PAR_LIBRARIES - BLAS component libraries to be linked (multithreaded) 25 26 #============================================================================= 27 #
