[CMake] Toggle Absolute paths in Eclipse Generator

[Eric Noulard]

Hi Michele,

If you look into CMake ML history you'll find many discussions concerning
the ABSOLUTE vs RELATIVE path for generated build systems.

CMake had once an option for trying that, the support has been removed:
https://cmake.org/cmake/help/v3.7/variable/CMAKE_USE_RELATIVE_PATHS.html

So basically you cannot ask generate relative paths.

See:
https://cmake.org/Wiki/CMake_FAQ#Why_does_CMake_use_full_paths.2C_or_can_I_copy_my_build_tree.3F
