You really should not add a file from the output trees. What ends up
in unxlngi6.pro is already a processed result, not the actual source.

To create patches for external modules that get build as part of
building LibreOffice, use

* "dmake patch" to unpack the sources and apply already existing patches,
* do your changes to the file
* use "dmake create_patch" to create a patch to be included into the
makefile (rename it to a descriptive name and add it to PATCH_FILES

If it is meant as a correction to an already existing patch, please
use solenv/bin/patch_sanitizer.pl to reduce noise between the old and
new version of the patch.

(with new build system you use something like
make cmd="dmake patch"
previously you had to source the Environment file, but that was
integrated to a config.mk)

Indeed. You don't add the file, but you need to create a patch that
will be applied before building that module as described above.
