DELETE: QT3 support
ADD: SOFA-MISC_CMAKE_VERBOSE to log direct dependencies of each project and their compile definitions at the end of the configuration
CHANGE: SOFA-EXTERNAL_* usage has been clarified
ADD: project path is now added in their own include dirs (hence propagated to the projects using them), it was not the case for headers only projects (if their directory also contains an "include" folder it is added as well)
