SFCGAL gets linked into GDAL SVN and issues strange compiler message

[bmoskovi]

I'm getting a strange warning message while compiling GDAL SVN. There is no GDAL configure option for SFCGAL and yet SFCGAL gets linked into GDAL. Here is the info:
$ gdalinfo --version
GDAL 1.11dev, released 2013/04/13

$ sfcgal-config --version
1.0.3

This is probably due to the postgis config (that has the sfcgal option). I see a dep on liblwgeom here.

But there should be no dependency on SFCGAL.

I see. So, should I be worried about these warning messages? It would be a shame to uninstall the sfcgal option in postgis.

I think you can safely ignore this if your are not creating a package (i.e. installing on a system should be fine).

I will contact a postgis developer to try and remove this warning.
