# - 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
|
|
#
|
|
|
|

# Check_Fortran_Function_Exists macro) whether can link against that library
|
|
# combination using the name of a routine given by _name using the linker
|
|
# flags given by _flags. If the combination of libraries is found and passes
|
|
# the link test, LIBRARIES is set to the list of complete library paths that
|
|
# have been found. Otherwise, LIBRARIES is set to FALSE.
