Unable to compile KWidgetsAddons

In trying to test out a KWidgetsAddons patch, I find that I'm unable to compile it on KDE Neon dev unstable the code due to a CMake error:

CMake Error in autotests/CMakeLists.txt:
  No known features for CXX compiler


  version 5.4.0.

My g++ version looks okay:

$ g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609
