Qwt is an extension to the Qt GUI library from Troll Tech AS.  The Qwt
library contains widgets and components which are primarily useful
for technical and scientifical purposes. It includes a 2-D plotting
widget, different kinds of sliders, and much more.

Optional dependency: qt6
If installed, the package will include qt6 support.

Optional dependency: qt4
If installed, the package will include qt4 support.
Since the default SBo build of qt4 does not include support
for designer, no qwt designer plugin is installed for qt4.

If you're interested in developing software that uses qwt, you might
want to build this with EXAMPLES=yes in the environment. This will
compile the example and programs and install them in the doc dir.
