<![CDATA[Can't compile my dynamic lib if I include OpenGL on windows 10 but can on ubuntu]]>Hi Everyone, i post here because while I can compile without problems my dynamic lib (Qt 5.15.2) on my linux machine, as soon as I try to compile it on windows, if I include any opengl related modules I have hundreds of errors. But, I can compile and run all the OpenGL Qt examples without problems.
Here are some of the compiler outputs, (changing the compiler doesn't solve the problem, here mingw64):

All seams related to oleauto.h...
I hope I can find help here.
Thanks!
