[CMake] Forcing CMake to find static library

[Michael Ellery]

if you know exactly where the library is (via the ENV), then I guess you want to specify the NO_DEFAULT_PATH option to find_library. Alternatively, see if you can use the standard find module included with cmake:

https://github.com/Kitware/CMake/blob/master/Modules/FindLAPACK.cmake

..and in that case you could set LAPACK_ROOT using your ENV value.

HTH,
Mike
