I pretty much agree with Greg on this.
First, there is no way we are going to support two distinct build systems on
Second, I still don't quite get what the advantage of cmake over what we have
on linux is. What we have isn't all that nice, but it is at least conventional
so I feel like I can fix stuff when needed, compared to a whole new way of
I'd be much more interested in cmake if we seriously planned to make it "the
build system" on linux and windows.
Also, with all due respect, I'm concerned that if Helio puts this into place,
and the rest of us are lost with regard to it, that Helio might lose interest
leaving us in a bit of a quandry. This has occured, for instance, with the
"libtool integration" into the GDAL build system. Someone kindly did it, but
then left the project, leaving the rest of us having to support it even when
we weren't that keen on it in the first place.
In reviewing the RFC again (http://trac.osgeo.org/fdo/wiki/FDORfc21) I don't
really see the connection between shifting to cmake, and breaking our
reliance on local ThirdParty builds. Why can't we just change the existing
build system to more conveniently support use of external third party
I'm basically -0 on RFC 21 as I understand it.
