including 3rd party libraries when they are not needed!

[volcoma]

So by default the root cmake is trying to include the 3rdparty cmake which is trying to locate boost and stuff. This is not necessary when someone is using the library without the examples/benchmarks and tests.
You've been kind enough to provide a bunch of options to config that but even when all these are turned off it shouldn't even try to locate boost and etc.. I am trying to use rttr as a submodule but i've hit a wall with this since i cant configure from the outside and i am getting an annoying warning since im not using boost. Thank you.
