Subject: [PATCH] fix: Versions-Regex in run_mkimage.cmake an
 NINLIGHT_FW_VERSION verankern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Vorher traf die Regex das erste Stringliteral im generierten Header, unabhängig
vom Makronamen. Zusätzlich bricht ein leerer Regex-Treffer jetzt hörbar ab,
statt eine leere Version stillschweigend in den OTA-Trailer zu schreiben.
