If you're going to override the build directory with CMake like
that
to bypass the behavior (which you *should not do*), you actually will
need to set both the source directory (with -S) and the build
directory (with -B) to override the default setting that the macro
sets.
I assure you that CMake accepts a lone .. as equivalent to -S.. even to
override a previous -S setting. I tried it and it builds perfectly fine. It
might not be documented to work, but it works.
But note that attempting to force an in-source build or the old
behavior will eventually break, since CMake upstream intends to
disallow this eventually (hence all the warnings it throws when you
try to do that). And a number of projects are already manually
attempting to break legacy behavior in their CMakeLists.
CMake does not warn about "%{cmake_kf5} .. -B.". See the build.log files in
the linked build.
