# - Find BLAS library # This module finds an installed fortran library that implements the BLAS # linear-algebra interface (see http://www.netlib.org/blas/). # The list of libraries searched for is taken # from the autoconf macro file, acx_blas.m4 (distributed at # http://ac-archive.sourceforge.net/ac-archive/acx_blas.html). # # This module sets the following variables: # BLAS_FOUND - set to true if a library implementing the BLAS interface # is found # BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l # and -L). # BLAS_LIBRARIES - uncached list of libraries (using full path name) to # link against to use BLAS # BLAS95_LIBRARIES - uncached list of libraries (using full path name) # to link against to use BLAS95 interface # BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface # is found # BLA_STATIC if set on this determines what kind of linkage we do (static) # BLA_VENDOR if set checks only the specified vendor, if not set checks # all the possibilities # BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK ########## ### List of vendors (BLA_VENDOR) valid in this module ## ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread model, lp64 model), ## Intel( older versions of mkl 32 and 64 bit), ACML,Apple, NAS, Generic # C/CXX should be enabled to use Intel mkl #============================================================================= # Copyright 2007-2009 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distributed this file outside of CMake, substitute the full # License text for the above reference.) get_property(_LANGUAGES_ GLOBAL PROPERTY ENABLED_LANGUAGES) include(CheckFunctionExists) macro(Check_Fortran_Libraries LIBRARIES _prefix _name _flags _list _threads) # This macro checks for the existence of the combination of fortran libraries # given by _list.
