Are you using a VPATH build?  That was the only build option that was
causing me problems on Debian GID even with the tweaks proposed by
Andres in a .lcovrc.  Non-vpath under configure and meson worked
unpatched.  With vpath under configure, that worked but the
directories were in a weird state (contrib/ missing from the root
patch, $HOME included).  meson was much slower than the two others.

I have also tried a few more experiments on Fedora 34 lately, that
points to even newer versions of all these tools.  Things are even
more broken moving forward for meson, vpath and non-vpath.  This is
testing things with an unpatched PG tree, just mentioning that it
does not seem to get better as time goes..
