[Omake] Out-of-tree builds

[Phil Endecott]

Hi,

Has any thought been given to using omake for out-of-tree builds of C / 
C++ programs?  My motivation is supporting cross-compilation to 
multiple architectures from the same source tree, e.g.

    |
    +-- src
    |
    +-- build_x86
    |
    +-- build_arm

src contains all the .c and .h files.  I want to be able to cd into one 
of the build directories and omake there to generate 
architecture-specific object files and executables.  The build 
directories would contain minimal OMakefiles defining the tool prefix.

The same sort of arangement is useful for debug builds in one place and 
production builds in another, and so on.

It would be great if someone had already found the simplest way to do 
this, or else could suggest where I should start.

Thanks,

Phil.
