One way to fix this might be to set the cmake property
Fortan_MODULE_DIRECTORY to something on the static library. Then the two
writes won't conflict. See the Fortran_MODULE_DIRECTORY cmake
property docs for more info. I am just trying it with
${CMAKE_CURRENT_BINARY_DIR}/${LAPACKLIB}_static_modules and two files
get created in different dirs. Ok to commit this?
