compile oscem with cmake, revision is not counting up

when i compile with cmake, the revision stays on 11760, but the commit number is always changing like it should.

-- revision: 11760 -- commit: 77c5f266

testet with the prvious commit and with the newest one. the revision stays on 11760. and in the webif it also stays on 11760:

VU+ Ultimo4K r11760@7c3b3357

this oscam is from the previous build few minutes ago, before the newest commit.

till 11760, it worked with the correct revision number.

do i have change something when i compile, or is it a bug?
