And? of course I know that.

I didn't do it for fun, I've created all these macros because I need a
build system as simple as possible with high level functionnalities and
I think it can help people to switch to CMake if parts of it was integrated

Why do I need something like this?

OpenWengo integrates FFmpeg, cURL, OpenSSL, LibGaim, GLib, Boost,
PortAudio, Qt4, TinyXML, oSIP, oRTP, eXosip + all the OS specific libs:
DirectX, V4L, XVideo, ALSA, OSS, QuickTime... + in some extend
IAXClient, Java libs, Objective-C, XUL/XPCOM...
+ of course we have a lot of internal libraries
In the future we will integrate even more stuff: VNC, libjingle, GTK+...
And everything should compile and work under Windows (MSVC), Linux (GCC)
and MacOSX (GCC)
We have more than 100 CMakeLists.txt and for now we have 2 build system:
CMake + SCons (an extended version by us). In the past we were using
QMake aswell.
A clean checkout from the trunk is more than 200MB and something like 10 
people fulltime are working on it...


This is an improvement over CMake so don't you think there might be some
nice ideas and improvements that can be added to CMake?
