Did you execute the make command after configuration? 

The build steps should look something like this. 

1. git clone https://github.com/NIRALUser/DTIPrep.git
2. mkdir DTIPrep-build; cd DTIPrep-build
3. ccmake ../DTIPrep
4. make

I'm running Ubuntu Xenial and have intalled Qt5 Qt4 following the instruction here

https://wiki.qt.io/Install_Qt_5_on_Ubuntu

error message seems to be that I need at least qt4.6  ??
