Additional context

• Nanoflann (including 1.5.5) doesn't seem to support gcc13?
• Blocker for alice-vision: init at 3.0.0, add 3.1.0 #256115 / Add AliceVision #224262

Oh, I was wrong, there's no issue in 1.5.5: the alice-vision PR overrides nanoflann's src to 1.4.X

Nanoflann builds just fine on master & releases.
