I think in this case you also don't need make clean (or distclean). 

Actually I use clean very seldom nowadays, also because cmake generates very 
complete dependencies (so why should I make clean ?)
And if I want to build something really from scratch, I just create a new 
build dir and use this (or get a fresh checkout to have exactly what is in 
the vcs).

P.S. if you really want to save typing, create the builddir as subdir of the 
source dir and name it just "b"
