Serghei,
I think I found a cmake error in knetworkmanager:
-- checking for 'Qt'
CMake Error at cmake/modules/FindQt.cmake:91 (check_cxx_source_compiles):
Unknown CMake command "check_cxx_source_compiles".
Call Stack (most recent call first):
ConfigureChecks.cmake:43 (find_package)
CMakeLists.txt:49 (include)
-- Configuring incomplete, errors occurred!
Aborting...
