fix: move to modern cmake and fix dev4 slot on the way

I noticed that the dev4 slot was having a problem running tests on clang due to a missing libomp.so. Up to Moore that library was correctly populated in the LD_LIBRARY_PATH so I figured it's likely a problem of MooreAnalysis still being old style cmake and figured the right rabbit hole to jump into is to move MooreAnalysis to modern cmake...

Not sure if I did it correctly though, so would be really grateful if @clemenci could have a look over this change.

(locally, it does compile, and all tests now pass)
