It's fine and I encourage having the qwt headers installed into their
own subdirectory.  That's how it's packaged for Debian/Ubuntu, and when
you compile from the source tarball, it does it too. (Though the
directory is not named qwt).

The qwt configuration script looks to be working finally.  If you want
to compile the gr-qtgui component to test, do the following:

1) Uncomment the #GRC_GR_QTGUI line in configure.ac, and re-run
bootstrap. (Right now the component is disabled for everybody.)

2) Add the two following lines to your ./configure script command line:

./configure --with-qwt-incdir=... --with-qwt-libdir=...

Replace the dots with the actual directory path that the include files
are installed into and the path the qwt library is installed into.  It's
unfortunate, but every distribution is putting these files into a
different place, and there is no way for the configure script to find
them automatically.

For example, if you install qwt from the sourceforge tarball, you'd have
to do:

$ ./configure --with-qwt-incdir=/usr/local/qwt/include \
              --with-qwt-libdir=/usr/local/qwt/lib

All this being said, gr-qtgui doesn't do anything useful yet :-) so
don't go looking for QT versions of all the wxPython stuff we already
have.  However, the QWT library has a very rich set of widgets and
eventually we'll be using these to display GNU Radio flow-graph
generated output.
