Wrong SFCGAL version used for compiling PostGIS 3.6.0 on Ubuntu?

[Scott]

On debian 12, PG 15, gdal 3.6.2 is the latest system pkg.

However, I've built PostGIS 3.5.3 with non-system pkg GDAL 3.11.3. That 
GDAL version is built with the latest non-system pkg geos 3.14 and 
sfcgal 2.3.0.

I can build PostGIS with the latest non-system pkg GDAL, but not the 
latest non-system pkg geos/sfcgal. Kinda weird.

SELECT postgis_full_version();

POSTGIS="3.5.3 aab5f55" [EXTENSION]
PGSQL="150"
GEOS="3.11.1-CAPI-1.17.1"
