All of these fail because the tests of kconfig don't build. I'm wondering why 
not all AppImage builds of all projects fail.

The cause for the failing (or highly unstable) builds of the tests of kconfig 
is an error in the test design. Here's what I wrote late last night in
#kde-craft:kde.org.

===
There is a pair of tests, e.g. Test8 and Test8_cmake where the latter is 
supposed to test that cmake can generate a .kcfgc file. The problem is that 
both tests share the same test8main.cpp which includes a test8a.h. This 
test8a.h is generated via test8a.kcfg[c] for Test8, but for Test8_cmake 
test8a_cmake.h is generated via a test8a_cmake.kcfg[c]. If for some reason 
Test8_cmake is built before Test8 then test8main.cpp doesn't find test8a.h. I'm 
not yet sure how to fix this. Maybe we need to create patched copies of 
testXmain.cpp which includes a testXx_cmake.h instead of a testXx.h. Or maybe 
we put both tests in separate subdirs and don't append _cmake to the files used 
for the TestX_cmake tests. That's feels like a cleaner solution also because 
it better isolates the two tests from each other.
===

With make the problem doesn't seem to occur because it looks like the Makefiles 
serialize building of Test8 and Test8_cmake so that Test8_cmake is always 
built after Test8 where Test8 creates the headers that Test8_cmake uses. With 
ninja the builds of both targets don't seem to be serialized so that 
Test8_cmake could be built before Test8. -> Fail!
