[Qgis-developer] cmake fails

[Paolo Cavallini]

Hi all,
my usual cmake ../ now fails (Deian sid, both 2.18 and master) with:
===
CMake Error: The following variables are used in this project, but they
are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the
CMake files:
QTKEYCHAIN_INCLUDE_DIR
   used as include directory in directory /usr/local/src/qgis/QGIS/src/core
===

In CMakeFiles/CMakeError.log I get:
===
Determining if the function openpty exists failed with the following output:

I have installed gnulib, which contains openpty (it is not a
dependency), but this does not solve it.
I'd be grateful of any hint.
All the best.
