> About 2: recently, chainned CMakeLists changed from:

> To:
> add_subdirectory(child-folder)
> First one overrides defauld build dir (cmake_current_binary_dir) with
> source dir, so it forces an in-source compilation.
> Now, it will be under binary_dir.
> So for out-of-source compilation (mkdir build + cmake ..) all generated
> files will be under build tree
> (Nevertheless, cmake . will maitain in-source style for backward

> Y love this change, but it will bite us in some ways (hardcoded relative
> paths, in-source dependencies (=config files)).
> Workaround? Just build in source, so...

> Therefore, as long as not al cmakelists took this change, will be the

> Just to adapt it if it is part of my changeset (so at least I test the

> So, for example, if we have:
> jderobot/a/b/c (directories)
> And b is just a cmakelist with add_subdirectory(c)
> Could this cmakelists disapear in favor of
