Hi Andy,

Thanks for the current dir info.

In my MS VC++ 6.0 the current file name in the title bar appears as
C:\...\foo.cpp
This is wonderful when you develop on 320x200 pixel resolution, but in
today's environments you usually have lots of empty space in the title bar. 
As I do not know how to change the title bar, I would still like to know
where my project is located (especially when switching back and forth
between the cvs main trunk version of a project and one with local changes).

Putting the path into the workspace name gives me this information.

This is CMAKE_CURRENT_SOURCE_DIR. There is also
CMAKE_CURRENT_BINARY_DIR.

What is wrong with cmake variable PROJECT_NAME?
Why would you want to store project name to be path to source?
