No, but it does cause more recompilation than a plain make. Sometimes
though running configure is necessary.

I suggest to add -nomake examples -nomake demos to the configure line.
This disables building of the examples and demos which takes quite a lot
of time because qmake is so slow and is run for each of them. Also if
you don't want to distribute your Qt it might make sense to add -release
or -debug to build only debug or release libraries (default is building
both).  That should help your compilation times quite a bit.
