I'm trying to build a Qt 5.9 project on Windows with MSVC2017 64bit and using prebuilt Qt binaries. The project depends on QNanoPainter to create custom items which uses NanoVG as its rendering backend that makes raw OpenGL calls.
When trying to build it seems like its linking to system version OpenGL, which on Windows is 1.0, and return lots of unresolved external symbols, that, if I'm not mistaken, are all functions not present on OpenGL 1.0. You can see a list of the unresolved symbols below.
I've already tried various solutions like adding LIBS += opengl32.lib to my .pro file but it keeps linking to system version. GPU drivers are updated to latest version. It's not a problem of not regenerated Makefiles since I run qmake each time I modified the .pro.
How could I link the correct OpenGL version so that compilation returns successfully?

It's not a duplicate of Unresolved external symbols - Qt creator, I run qmake after each edit of .pro file as I stated above.
