1# - Find LAPACK library
2# This module finds an installed fortran library that implements the LAPACK
3# linear-algebra interface (see http://www.netlib.org/lapack/).
4#
5# The approach follows that taken for the autoconf macro file, acx_lapack.m4
6# (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html).
7#
8# This module sets the following variables:
9#  LAPACK_FOUND - set to true if a library implementing the LAPACK interface
10#    is found
11#  LAPACK_LINKER_FLAGS - uncached list of required linker flags (excluding -l
12#    and -L).
13#  LAPACK_LIBRARIES - uncached list of libraries (using full path name) to
14#    link against to use LAPACK
15#  LAPACK95_LIBRARIES - uncached list of libraries (using full path name) to
16#    link against to use LAPACK95
17#  LAPACK95_FOUND - set to true if a library implementing the LAPACK f95
18#    interface is found
19#  BLA_STATIC  if set on this determines what kind of linkage we do (static)
20#  BLA_VENDOR  if set checks only the specified vendor, if not set checks
21#     all the possibilities
22#  BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK
23### List of vendors (BLA_VENDOR) valid in this module
24##  Intel(mkl), ACML,Apple, NAS, Generic
