Use FindPython module built into cmake. Bump requirement to CMake 3.15 for Python3_FIND_VIRTUALENV()

Remvoe -D that had been passed in front of each entry of add_compile_definitions, this lead to '-D-D<value>'

Rework cmake, the original plan was to maybe be able to use conan targets with the same name (that's why 3ps had names like apr::apr),
but it's safer and saner to put the LL 3ps under the ll:: prefix.
This also allows means it is possible to get rid of that bad "if( TRAGET ...) return() endif()" pattern and rather use include_guard().

Fix warning supression for Linux/OSX, this was broken after the first round of cmake changes on Windows.
-Wno-unused-but-set-variable/-Wno-unused-variable moved from just Linux to also OSX (clang) as there's a lot of those
in the code where newer xcode complains. Fixing all those places is going beyond the scope of modernizing cmake.

this everythig was over the place how it was set, worse even with wrong
functions like:
- add_definitions( /arch:SSE2 )
- add_definitions(/WX)
Those are each options to cl, not definitons.

Change projects to cmake targetsto get rid of havig to hardcore
include directories and link libraries in consumer projects.
