I remember trying to find out about CMake back when Albert originally
brought up the idea of using a new build tool...
There are areas were I see SCons as lacking, though speed is not one of them
(it's a little slow on my Atom netbook, but it flies on a real machine)...
I'd be interested in CMake, if it:
* is able to do cross compiling (build i386 Linux, Windows, OSX from our
64-bit Linux server) or supports some kind of distributed build set-up to do
this where builds can be built and uploaded from mulitple machines to a
server with results.
* solves some packaging problems (can make .rpm, .deb, .dmg, .msi)
* makes it easier to support autobuilds (nightly snaps or when the repo
changes)
* creates projects that can be used from within Eclipse CDT
* easily extends to handle new build flags and library/header deps
* does not make it harder for mixxx devs to troubleshoot people's build
config problems
I looked at the CMake website, and to be frank I find the site (even with
the new layout) a bit impenetrable; could not find a feature matrix,
comparison with other build systems (both SCons and Waf have docs
comparing/contrasting with other systems), or mention of any of the above
things in the FAQ doc for example...
If there is some consensus that it's significantly better, then I have no
objection to it being added to the repo to run in parallel to SCons, until I
have a chance to play with it over the holidays (if I get to take any that
is), I will abstain from voting for or against it as a new build standard.
Helio, you should post your cmake patch up to the list or work with Claudio
to merge with his and share the results... no reason you guys shouldn't at
least get a better cmake out of it, even if we don't eventually adopt cmake
as a defacto standard for Mixxx...
Cheers,
