[CMake] Setting Working Directory for Debugging in MS VC++ via CMake

[Steve Johns]

Recently, in an MS VC++ 7.1 (.NET 2003) build prepared using CMake, I've had 
a problem with the application finding a config file that it needs to read 
at startup.  Even though I placed the file in the app's startup dir (i.e. 
'blahblah/Debug', when debugging ) the app was not finding the file.  This 
despite the fact that when the app was run outside the IDE (e.g. simply from 
a command window) it always found the file (in the startup dir) without a 
problem.

Ultimately it was found that manually setting the 'Working Directory' 
property (in the property pane) for the ALL_BUILD target to 'blahblah/Debug' 
would enable the config file to be found.

Note:  setting the 'Working Directory' property for the single project that 
creates the application executable DID NOT work.

So, now my question is:

What can I do in CMake, or in CMakeLists.txt files, to set that (debugging) 
'Working Directory' property for the ALL_BUILD target automatically as part 
of the CMake build process?

Thanks kindly to anyone who can shed some light on this for me ...
