Qt5.5 static build cannot find -IGL on ubuntu14
I have compiled qt 5.5 for static building and it works fine.
However, when I add the widgets "QT += widgets" in the pro file I get the link error "cannot find -IGL"
From what I read this is to do with the Open GL libs. I have tried the following:
sudo apt-get install libglu1-mesa-dev
sudo apt-get install libgl1-mesa-dev
But no luck here... I am wondering if I need a static version of this? or maybe a symlink is missing, but I can't figure out the next step :(
