# - Find LAPACK library | |
# This module finds an installed fortran library that implements the LAPACK | |
# linear-algebra interface (see http://www.netlib.org/lapack/). | |
# | |
# The approach follows that taken for the autoconf macro file, acx_lapack.m4 | |
# (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html). | |
# | |
# This module sets the following variables: | |
# LAPACK_FOUND - set to true if a library implementing the LAPACK interface | |
# is found | |
# LAPACK_LINKER_FLAGS - uncached list of required linker flags (excluding -l | |
# and -L). | |
# LAPACK_LIBRARIES - uncached list of libraries (using full path name) to | |
# link against to use LAPACK | |
# LAPACK95_LIBRARIES - uncached list of libraries (using full path name) to | |
# link against to use LAPACK95 | |
# LAPACK95_FOUND - set to true if a library implementing the LAPACK 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 | |
