| # - 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 posibilities |
| # BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK |
