Also that the qmake file is well-formed. It's possible to have .pro files
(I have one that dates from the Qt3 era) that will build perfectly with
qmake, but which Creator can't follow well enough to find the include files.

If there are parser problems, check the #include statements in the file,
hover over them to make sure Creator has found them.

(It would be nice to have some way to see parser errors from
within Creator, though, rather than having to intuit them from
behaviour and env-variable triggered logging).
