Metaini expansion takes very long
I'm trying to refactor testing in dune-gdt. For this I need bunch of variations of function spaces that will be the type parameter to a lot of different test sources. I have a working metaini that does what I want. However calling cmake .
in the builddir with this file takes about 20 minutes.
I've isolated the file into the testtools-mwe package: rene.milk/dune-testtools-mwe@3cce3dc8
If I do that here the cmake call "only" takes 2.5 minutes.
Is this to be expected? Am I doing it wrong? Or is it a bug? Testtools is on the 2.4 branch.
