QwtPolar 1.0.1

I have a bit of a problem installing QwtPolar library into my Qt 4.8.1(mingw). When I'm trying to make with mingw32, it throws an error like:
In file included from qwt_polar_fitter.cpp9:
qwt_polar_fitter.h:13:30: error qwt _curve_fitter.h: No such file or directory
I know that I have to somehow include path to the qwt library, but I have no clue on how to do it, nothing works for me what I found on internet. Can anybody help me how to do it?

Any help appreciate.

Unfortunately, I'm not here to give you an answer but to refresh your question.
I'm also trying to compile QWTPolar but I'm getting "no such file or directory" errors.
(I'm on Windows on Qt5, Qwt6.1.0 and with msvc, but the errors are the same)

I thoroughly followed the QWT build and install procedure; and for testing, I copied a qwt example (oscilloscope) into a seperate folder, added the "include ( $$(QWT_ROOT)/features/qwt.prf )" line in the project file (as said in the QWT documentation) and everything worked perfectly.

But this include doesn't help the QwtPolar building.
Now, as Henrich, all solutions I found on the Internet didn't help me with the building.

Thanks for your thoughts !
