Moreover, added 00015 # code to mark variable as advanced and only show them to the user if 00016 # no required library was found. If the found library is cblas, the corresponding 00017 # header file cblas.h is searched as well. Therefore, added the BLAS_INCLUDE_DIR 00018 # variable which is only defined if required. 00019 # 00020 # This module sets the following variables: 00021 # BLAS_FOUND - set to true if a library implementing the BLAS interface 00022 # is found 00023 # BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l 00024 # and -L). 00025 # BLAS_LIBRARIES - uncached list of libraries (using full path name) to 00026 # link against to use BLAS 00027 # BLAS_INCLUDE_DIR - uncached list of include directories for C libraries 00028 # BLAS95_LIBRARIES - uncached list of libraries (using full path name) 00029 # to link against to use BLAS95 interface 00030 # BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface 00031 # is found 00032 # BLA_STATIC if set on this determines what kind of linkage we do (static) 00033 # BLA_VENDOR if set checks only the specified vendor, if not set checks 00034 # all the possibilities 00035 # BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK 00036 # 00037 # List of vendors (BLA_VENDOR) valid in this module 00038 # 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), 00039 # Intel( older versions of mkl 32 and 64 bit), ACML,ACML_MP,Apple, NAS, Generic 00040 # C/CXX should be enabled to use Intel mkl 00041 # 00042 # @verbatim 00043 # Copyright 2007-2009 Kitware, Inc. 00044 # All rights reserved. 00045 # 00046 # Redistribution and use in source and binary forms, with or without 00047 # modification, are permitted provided that the following conditions 00048 # are met: 00049 # 00050 # * Redistributions of source code must retain the above copyright 00051 # notice, this list of conditions and the following disclaimer. 00052 # 00053 # * Redistributions in binary form must reproduce the above copyright 00054 # notice, this list of conditions and the following disclaimer in the 00055 # documentation and/or other materials provided with the distribution. 00056 # 00057 # * Neither the names of Kitware, Inc., the Insight Software Consortium, 00058 # nor the names of their contributors may be used to endorse or promote 00059 # products derived from this software without specific prior written 00060 # permission. 00061 # 00062 # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS 00063 # "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT 00064 # LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR 00065 # A PARTICULAR PURPOSE ARE DISCLAIMED.
