How to move the build out of the source directory?

[Atanas Atanasov]

Hello GNUsteppers,

        I wonder if somebody can advice me on how to move the build of a 
GNUstep 
application out of the source directory. I looked at the GNUstep 
documentation but I couldn't find anything about it. 
        My application has several subprojects. What I want to achieve is to 
have the 
complete build tree (all obj dirs and the .app) not inside, but in parallel 
to the source dir. The reason I need this is because I am testing my app both 
on Linux and Solaris, and I want to have one source location for both OS (e.g 
on a nfs share) and not have to clean the build each time I want to build it 
for the other OS.

Has anyone come across this problem?
