For cleaning accidents in a git source directory I have the following command memorized: "git clean -dfx" but you would want to be careful about using it so that you don't accidentally delete any of your pending work or associated important files that you might have in the source directory!

Re: Unable to compile KWidgetsAddons
I'm somewhat embarrassed to admit that I was doing an in-source build and no amount of `make clean` and `rm CMakeCache.txt` fixed the problem, but doing a proper out-of-source build worked just fine. That'll teach me...

I'm asking for the full cmake log after cleaning your build directory, because the first line of a cmake log should be (kdesrc) tsdgeos@xps:~/devel/kde/kwidgetsaddons/build:master$ cmake .. -- The C compiler identification is GNU 7.3.1 not -- Looking at your cmake log i'm 97% sure it's not a clean build directory you're using.

But I don't really have enough CMake expertise to be able to pin down why it doesn't understand what compiler features are available for gcc or what code is asking for these features in the first place.

Do you have that error for just that one framework? Make sure you've fetched any relevant build deps.
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 "GNU" version 5.4.0.
