I adjusted
FindLAPACKE.cmaketo use PkgConf to find lapacke. The problem with the current implementation on Gentoo is that the libraries are not named liblapacke and liblapack. On Gentoo the name of the library depends on the installed package, allowing to install multiple lapack packages side-by-side. To show the differences I quote from the *.pc files:lapacke-reference
lapack-reference
atlas
Please let me know if there is anything to improve this patch.
