[Dev-C++] environment variables

[<or...@vp...>]

Hello!

Does Dev-C++ support environment variables at giving include and lib 
directories?

If yes how?
If no, how can it be emulated?

It would be very good to support it, because I am using 2 external 
libraries (wxWindows(not the DevPak!) and Crystal Space 3D SDK) for my 
project, and I want to publish it, but the include and lib directories 
are absolute in Dev-C++, and it would be easier for others if they only 
set an environment variable, and just hit compile.
