# FindLAPACK
|
|
# ----------
|
|
#
|
|
# 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 # Intel(mkl),
|
|
# OpenBLAS, ACML,Apple, NAS, Generic
