When I say "build environment", I mean the tools available for compiling 
and linking.

On Windows we currently provide full support only for MS Visual Studio 
2010 with the native VS2010 toolset.

On GNU/Linux we currently provide support primarily for gcc, though icpc 
can also be used. clang hasn't been tested yet as far as I know.

An interesting project might be to implement support for some Windows 
build environment other than MS Visual Studio, preferably a free one, 
with the goal that users can compile their own version of POV-Ray 
without having to acquire a license for Microsoft's proprietary software.

In-source builds suck anyway :-P

Currently there's no code generation from POV-Ray itself, but some 
libraries generate config files as part of their build process (IIRC 
this is the case for libtiff and libpng), or even build & run small 
software tools to generate code (this is the case for OpenEXR).

For POV-Ray's Windows UI there are two separate DLL projects, one of 
which isn't part of the official 3.7.0 release due to licensing issues.

Aside from that it's just compile, link & run.

Ah, and there's a deliberate compile error you will bump into if you 
forget to set some preprocessor macros intended to identify the 
individual responsible for the (presumably unofficial) build.
