[webkit-dev] Buildsystem cleanup

[Salisbury, Mark]

I'm glad to see there is some interest in using CMake to build on windows.  Using CMake has made working on Windows easier for me (thank you Patrick!)...  somewhere on webkit.org there's a page about ideas for making life on windows easier and I think the CMake build system addresses a number of the concerns.

Patrick uploaded a patch (https://bugs.webkit.org/show_bug.cgi?id=72816) that uses a strategy of separate CMake platforms for the Apple Windows build, for Windows Cairo, and for Windows CE.  I think there's a lot of duplication in having 3 separate CMake platforms for Windows builds.

I put another patch out there which creates a single PlatformWin.  Build switches passed to CMake then generate the platform you want (Apple, WinCairo - in the future WinCE).  I'm curious for those who are interested in CMake for Windows builds which approach they think makes more sense.  Duplication but full isolation or no duplication but more opportunity to collide.  Both patches are still works in progress.
