Update CMake/YCM export options

[PeterBowman]

YCM 0.11 will introduce a bunch of new features regarding how targets are treated upon export:

• https://github.com/robotology/ycm/issues/262: set(CMAKE_EXPORT_PACKAGE_REGISTRY ON) instead of calling export(PACKAGE) explicitly (example).
  • affects most repos
• https://github.com/robotology/ycm/issues/263: add NO_EXPORT option to install_basic_package_files() in order to instruct YCM not to export targets when there are actually none (example). Addresses https://github.com/roboticslab-uc3m/project-generator/issues/19.

Seems like YCM 0.11 might bump minimum required CMake version to 3.12: https://github.com/robotology/ycm/issues/261. Thus, requiring YCM 0.11+ in our repos would break support for Ubuntu 16.04 unless users are instructed to pull the latest (CMake 3.15) release from the new https://apt.kitware.com/ repository.

See announcement and a brief CMake 3.12 migration guide at https://github.com/robotology/QA/issues/364.

YCM 0.11 has been released today: https://github.com/robotology/ycm/releases/tag/v0.11.0.

I'm turning this issue into an announcement. Since YCM already requires CMake 3.12, we strongly suggest to upgrade CMake accordingly. This is best achieved using the new Kitware PPA: ref (CMake 3.16.0). Also, a pip alternative exists: ref (CMake 3.15.3).

Also, YCM 0.11 introduces the CMake option YCM_EP_INSTALL_DIR to change where the subprojects will be installed (default: install/). I'd consider this on superbuild repos, e.g. asibot-main.

Just to let you know, the variable YCM_EP_INSTALL_DIR is quite experimental, and we did not test it extensively. In particular, I am not really sure if it works correctly YCM_EP_INSTALL_DIR is a prefix that also contains some libraries that are used as dependency of the superbuild.

@traversaro that's good to know, thanks!
