Description of problem:
The current version of Qwt works only with Qt4. Some errors are produced while
build a Qt5 project using it in QtCreator.
Version-Release number of selected component (if applicable):
6.1.0
How reproducible:
Always
Steps to Reproduce:
1. Create a Qwt plot
2. Configure properly .pro file in QtCreator (add LIBS += -lqwt)
3. Compile. Segmentation fault is produced
Actual results:
The Qwt Fedora package was compiled using Qt4 instead of Qt5
Expected results:
Depending of the Qt version of the project, there would be a Qwt for it

Hrm, last I tried, qwt didn't support qt5
I'll check again.

I'll try to contact upstream to find out what's going wrong here.

I found upstream has a couple of Qt-5.4-specific fixes committed since
6.1.1 release, which look promising.

Oh, it's too bad, upstream's Qt5 support is ... poor.
They currently do not support parallel-installs of both Qt4 and Qt5
versions (library names and support files are all named the same).
Fixing this is likely a prerequisite before we can ship a qt5-enabled
qwt build in fedora.
