[Bf-committers] Removing Build Systems

[vekoon]

I guess it much depends on personal preference, i.e. people using 
makefiles will say no and people using either scons or cmake will be ok. 
I say this because being one of the latter I'd agree totally with this.

On a side note, the minimal knowledge I acquired using SCons is not 
enough to determine this so I'm asking to SCons experts: couldn't it be 
possible to add an additional layer to scons build (like some flags) 
that from SConscript files could generate CMake equivalents? So that one 
can adopt SCons as the only (official) build system supported but if you 
want native project files you can still have them without adding up 
efforts for devs to maintain 2 build systems.
