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