I have installed Qt 4.8.5 with Qt-creator 2.8.1 on CentOS 6.9 system.

Now I am trying to compile QWT 6.1.0 library on my system.

However, I am getting the error qt libraries qmetatype.h, qdebug.h can not be found as shown in the attached image.

Any suggestion on how to resolve this issue? qwt_installation.jpg
