So this isn't correct. Not all the files under sheets/ are annotated at
the top to be LGPL. Instead, some in dialogs (which are needed) and two
files in tests (which aren't necessarily needed) are annotated at the
top to be GPL.

The files in sheets/dialogs/ imply that Sheets turns into GPL unless you
rewrite those ui files. This is a bit sad and silly because rewriting
a .ui file is of course not difficult, and at the same time it means
that using a non-patched Calligra/sheets/* with just the CMakeFile.txt
adaptations to turn it into a public library with a mini SDK by exposing
its .h files; isn't possible (I would have to make the .ui files again).

I answered I myself: because of the .ui files I can't assume this (I
know, sorry, the coffee is now being applied to the developer).

I however wonder whether you guys are ok with relicensing? :-)

At least my grep and cut magic looks right. But perhaps the command
missed a file?

Kind regards and apologizes for the first Monday-morning E-mail.
