I am trying to compile wxWidget on Ubuntu 20.04, but I have run into some errors.
I have installed gtk3 with the following command which was suggested in the documentation:
sudo apt install libgtk-3-dev
Running ../configure --with-gtk=3 --with-opengl gives an error:
checking for OpenGL headers... found in /usr/include
checking for GL/gl.h... yes
checking for GL/glu.h... no
configure: error: OpenGL libraries not available
Is their anything I am missing?
