Hello!
First of all, the root filesystem is created with ptxdist (if it is
known to you).

CMAKE_FIND_ROOT_PATH and some other variables are defined.
No QT_... variables are set. This works fine "automatically".

The file is attached and IMHO it is not overloaded.

Sure, that is always a problem ;-)
So, I would be glad if you could have a look at the toolchain file and
we could improve cross compiling Qt projects with cmake.
Greats,
