Build variables

[acrap]

Where can i find build variables in codelite?
I don't know why, but environment variables don't work for me.

I've tried to add variable to environment variables:
build_dir=Build

And i've tried to use this in custom target:
cd $(build_dir)

But it doesn't work for me. If i change command to echo $(build_dir) i just see $(build_dir) in output.
Also, i've tried to use brackets {} instead (). It still doesn't work.
Anybody can help me?

Can you provide an example workspace with this setup? so I can debug it here?
