Draft: Use TangoCMakeModules

Use a shared set of CMake find modules which is included as a git submodule.

@dlacoste-esrf How should I update the example? Do you want that to use the TangoCMakeModules as well? I guess I could add a symlink back to the top level, but I am not sure how to test things.

sorry I'm just reading this now.

Excellent question! How about we move the example to a project of its own? this way we can have the modules as a git submodule as well, and we could have, in the future, ci and everything running on it?

@gscalamera, @bourtemb any opinions on this?
