Solved the problem by installing the “libglu1-mesa-dev” package.
@sudo apt-get install libglu1-mesa-dev -y@

If it matters to you..... On Fedora 18, I used:

@yum groupinstall "Development Tools"
yum install mesa-libGL-devel@

Did you ever get this resolved? I installed this on 64bit centos and ran the two commands above to install those rpms but it still does not work

You need to find out what packages you need to build OpenGL programs in CentOS (e.g. try http://www.qtcentre.org/threads/58151-IGL-error-in-CentOS-6 )

I have ran these commands

@yum install mesa-libGL-devel mesa-libGLU-devel
yum install qt
yum install qt-creator@

and then installed Qt 5.4.1 for Android (Linux 64-bit, 616 MB)

I am on centos 7 x64 but it still does not work
