Is it possible to acquire the workspace path in Xcode 4 via an environment variable

Question

I can't find anything workspace related in the Xcode Build Setting Reference.

Essentially I need something like $(WORKSPACE_DIR). If Xcode doesn't provide it, is there any way to define a custom user variable that could somehow accurately provide the workspace path in the event that the working workspace were to move (think branches etc)?

Answer 1

If your workspace is set up like:

//bla/bla/bla/workspace/{project directories}* 

then you can use

$(SRCROOT)/../

to get the workspace directory from a give project directory.

For example, if you want to have one project reference headers in another project:

Project Build Settings->User Header Search Paths => $(SRCROOT)/../SomeLibProj

(and set it to 'recursive' if you don't want to add every folder)
