+The GNUtoMS CMake module helps LAPACK provide MS-compatible DLLs on
+Windows when built with a free GNU Fortran compiler (e.g. MinGW).  If
+MS Visual Studio tools are installed when one configures LAPACK to
+build with GNU tools the module extends the shared library link rule.
+The extended rule creates both a GNU-style .dll.a import library and a
+MS-format .lib import library.
+
+LAPACK CMake code installs the import libraries for both formats.
+Applications built using CMake can be configured automatically to use
+the import libraries matching the target toolchain.
