Note: QtPdf build is disabled by user.

Note: The following modules are not being compiled in this configuration:
    pdf
    pdfwidgets

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
