[QGIS-Developer] Not able to build QGIS with 3D on Ubuntu 16.04

[matteo]

Hi all,

I'm writing this mail hoping to help somebody else that experienced the
same problem with Ubuntu 16.04 and the build of QGIS with Qt 5.9

Following the instructions on Martin's website I had to adjust some
small parameter:

1. **after** running ccmake and generating all the files I had to export
the variable

export CMAKE_INSTALL_PREFIX=/opt/qt59/lib/cmake/

2. then I could run cmake with all the flags

and finally QGIS has been compiled against Qt 5.9 version and I can use
the 3D ;)

Hope this could help other people

Cheers

Matteo
