What about musl here ?

Also, just like we have a comment for packages that need C++ support,
we should probably have a similar comment for packages that need
Fortran support. And of course, the documentation should be updated
accordingly.

No need to mention "libblas and liblapack" if that's all what the
package is installing. Specifying what is under what license is only
needed when multiple licenses are used.

Don't we generally use upper-case for ON/OFF in CMake packages ?

Thanks,
