Yes, I only changed remove the full path where TLIB_PATH was pointing and 
removed the files from editorD_SOURCES and added those two imaginary entries 
and removed many defines from editorD_CPPFLAGS to make it more clear. I 
could have also removed all the lib paths in AM_CPPFLAGS to make it even 
more clearer.

Alright, I can do that but could you tell me how to use global-target flags, 
instead of the per-target? Because this is the only way I have learned to do 
things from a tutorial.
