> Fortran - It could just be me, but IDEs struggle with it. If you have any global data it may as well not exist as far as the IDE is concerned, which makes dealing with such projects very hard.

You really should not have global data. Modules are the way to go and have been since Fortran90.

> CMake - I'm amazed it works at all. It looks great for simple toy projects and has the power to handle larger projects, but it seems to quickly become an ungodly mess of strange comments and rules that aren't spelled out - and you have no way of stepping into it and seeing what it's doing. I try to touch it as infrequently as possible. It feels like C macros, in a bad way.

I like how you wrote my feelings so accurately :D

Legacy code, just have to deal with it. This code predates F90.
