[gdal-dev] Error building GDAL 3.8.3: Installed GEOS not found during build

[Eric Patton]

I am running into an error while building gdal 3.8.3 from source - it seems GEOS (version 3.12.1) is not being found during the build, despite that fact it was completely installed from source with no errors. I'm using LInux Mint 20.3.

# GDAL build commands used:

$ cmake -DCMAKE_BUILD_TYPE=Release ..
(No obvious errors in output, GEOS seems to be located):

-- The following RECOMMENDED packages have been found:
* GEOS
Geometry Engine - Open Source (GDAL core dependency)

$ cmake --build .

# But that's strange:
$ which geos-config
/usr/local/bin/geos-config

$ geos-config --version
3.12.1

# Location of GEOS include dir:

$ cd /usr
$ find . -name "geos_c.h"

$ uname -a:

Please let me know if there's anything else I can post to help diagnose the error, thanks.
