# Find LAPACK library
|
||||
#
|
||||
# This module finds an installed library that implements the LAPACK
|
||||
# linear-algebra interface (see http://www.netlib.org/lapack/).
|
||||
# The approach follows mostly 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_INCLUDE_DIR - Directories containing the LAPACK header files
|
||||
# LAPACK_DEFINITIONS - Compilation options to use LAPACK
|
||||
# LAPACK_LINKER_FLAGS - Linker flags to use LAPACK (excluding -l
|
||||
# and -L).
|
||||
# LAPACK_LIBRARIES_DIR - Directories containing the LAPACK libraries.
|
||||
# May be null if LAPACK_LIBRARIES contains libraries name using full path.
|
||||
# LAPACK_LIBRARIES - List of libraries to link against LAPACK interface.
|
||||
# May be null if the compiler supports auto-link (e.g. VC++).
|
||||
# LAPACK_USE_FILE - The name of the cmake module to include to compile
|
||||
# applications or libraries using LAPACK.
|
||||
#
|
||||
# This module was modified by CGAL team:
|
||||
# - find libraries for a C++ compiler, instead of Fortran
|
||||
# - added LAPACK_INCLUDE_DIR, LAPACK_DEFINITIONS and LAPACK_LIBRARIES_DIR
|
||||
# - removed LAPACK95_LIBRARIES
