I one more quick point: I don't want to install the libraries to standard
locations because there may be multiple Fortran compilers installed on a
given system, and client code cannot be built and linked using a different
compiler than the library. Therefore the library and mod files and CMake
package-config files are disambiguated by adding the compiler ID to the
install path and package name. This way versions of the library built with
different compilers can be installed and accessible on the same system.
