fails to compile on Ubuntu 14.04

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Ubuntu 14.04
2. Install prerequisites for compiling ifcpluplus
3. Try to compile ifcplusplus

What is the expected output? What do you see instead?
I expect the to program to compile nicely.

Left with this qt linking problem after solving other compile stopping bugs.
