Add warnings to CMake build

[FG-TUM]

Is your feature request related to a problem? Please describe.
The old make-way to build ls1 featured lots of warning flags. Apparently, we did not really port this to CMake therefore there have been many new ones.

Describe the solution you'd like

• Add -Wall to the CMake target.
• Exclude super spammy warnings (e.g. copy from AutoPas)
• Silence warnings from dependencies.

Describe alternatives you've considered
