make uninstall

removes everything that has been installed.

It is very difficult to change the behavior of default targets.  What we 
could do is to add a new target 'allclean' that first executes 'uninstall' 
and then 'distclean'

Remember, those are wiki pages - feel free to add this information at the 
appropriate place ;)

I guess what you mean is described at the bottom of

https://projects.coin-or.org/BuildTools/wiki/user-configure

as "Performing a VPATH Compilation".
