Because I have two (more or less) independent projects, that joins the same
root! And I want to have two build process and packages created by cpack in the
end.

That's an option, that hurts less. My intention is to make the build process as
logical and convenient as possible to convince people to switch to cmake. So
reading ${MY_PROJECT_ROOT} is ok, but having ${CMAKE_SOURCE_DIR} would be
better at least, because it is documented. I am afraid that people write their
first CMakeLists.txt from a tutorial, add it with ADD_SUBDIRECORY() to the
projects CMakeLists.txt and nothing works as expected, as their
CMAKE_SOURCE_DIR is placed somewhere, but not at the root they expected.
