update docs and configure to reflect SFCGAL 1.1+ is required to build with SFCGAL

[robe]

Guys,

I'm assuming this is an intentional break, and I'm fine with that, but configure has got to be fixed and so are the docs.

After the latest winds of changes to sfcgal (I'm assuming this one in particular #3117 ) , I now get this error on winnie. I'm going to update her SFCGAL, but so others don't scratch their heads in plane, please update configure and docs to reflect the change: ​http://postgis.net/docs/manual-dev/postgis_installation.html#install_short_version

Thanks for the report, I'll edit SCGAL home page too.

[vmo]

… and actually release SFCGAL 1.2.0

[vmo]

Hold on, changing the patch to 1.1 first.

[vmo]

This one is for the already released SFCGAL 1.1

[vmo]

With the second patch you're good to go with SFCGAL 1.1

SFCGAL 1.2 comming soon.

[robe]

Committed at r13714. I'll close once I retest (after I have sfcgal updated to newer)

[robe]

confirmed configure change traps lower now. Get this from winnie now. I'll check again after I upgrade sfcgal:

configure: error: PostGIS requires SFCGAL >= 1.1.0 (found 1.0.5)

[robe]

upgrade winnie to sfcgal 1.1.0 and works fine now, all regresss pass so closing.
