Hi Pieter,

Sorry for the late reply. We are still working on 5.6. Currently the git
master contains several new patches to deal with this version. It
disables some libraries which are not required anymore via cmake. I'm
not sure if that fixes your Problem.

There are also still Problems on other platforms (VS2015 with internal
compiler errors,...) so still some work to do getting 5.6 completly
supported.

What you can also try, Open cmake and remove all qt related entries
except the QT5_INSTALL_PATH. Set the PATH to empty and rerun cmake.

Check if all variables are correct. You can also search in the
"CMakeCache.txt" file which contains all cached variables.

Best,
Jan
