There is code to remove the prefix CMAKE_SOURCE_DIR from __FILENAME__ paths
used for logging with LOGE() in the code. We need to make this match the value we use
in the debug source remapping from CFLAGS
We export the right path to use in the recipe with:
EXTRA_OECMAKE = "-DCMAKE_DEBUG_SRCDIR=/usr/src/debug/${PN}/${EXTENDPE}${PV}-${PR}/"
and we then patch this into the code instead of the broken use
of CMAKE_SOURCE_DIR since __FILENAME__ will match our path prefix
changes.
This also breaks reproducibility since the path length of the build directory
will currently change the output!
