Get trunk CP2K and build with lto (note, this requires checking=release,
PR45586) and a couple of minutes on a larger machine.
svn co svn://svn.code.sf.net/p/cp2k/code/trunk/cp2k cp2k
cd cp2k/makefiles/
cat ../arch/lto.sopt # and check all is appropriate (note blas/lapack linking)
make -j48 ARCH=lto VERSION=sopt
starting a fresh build goes with
make -j48 ARCH=lto VERSION=sopt realclean
