csv-plot: cmake doesn't mention need for qwt or allow path to be set

[junderwood]

This causes a problem in windows - cmake works, but the build fails with:

3>c:\users\j.underwood\code\cpp\source\snark\graphics\applications./csv_plot/curve_stream.h(38): fatal error C1083: Cannot open include file: 'qwt/qwt_plot_curve.h': No such file or directory

The other dependencies seem to be managed explicitly in cmake, like pcap, etc.

i tried to add finding qwt to cmake, but i expect it may not work on windows

csv-plot is only a first cut driven by volunteer after-hours work; currently we can afford very little development effort; there are so many features that you would perceive as missing (or buggy) that there is no point to create tickets on all of them; a better way would be to suggest your priorities and work on them as time permits

thus, there are 3 ways:

• depending on your priorities, you include building on windows into the next (or any) sprint
• you try to fix it on windows yourself (it may - or may not - take 5 minutes)
• you switch csv-plot off windows
