Unable to compile current version (50aa3184)

[aprokop]

I don't know what changed in the repo or recent SWIG, but it no longer compiles for me. For some reason, it does not seem to make compilation rules for the generated .f90 files, producing erros like

Fatal Error: Can't open module file ‘formatrix.mod’ for reading at (1): No such file or directory

I wanted to quickly test some performance with it.

I was able to compile by

diff --git a/cmake/SwigModules.cmake b/cmake/SwigModules.cmake

OK, it's actually uglier than that. I have to

1. configure with .f90
2. run make with .f90 which fails with not found .mod
3. change to f90
4. run make again for completion

@sethrj This is super weird.
