Add style formatting / linting for CMakeLists.txt

[oswinso]

The styling for our CMakeLists.txt is very varied and there isn't a standard right now, ie. parenthesis on newline or same line, how many spaces etc.

We should use a tool / linter / styler to make sure all our CMakeLists.txt are styled the same way.

Found a library that does this, don't know how to implement it though

That library doesn't seem to be maintained though... :(
