[cdt-dev] Expanding CDT build variables programmatically

[Mario Pierro <Mario.Pierro@xxxxxxx>]

Hello,

What is the correct way of programmatically expanding CDT build variables like ${ProjDirPath}?
I have tried to use 

VariablesPlugin.getDefault().getStringVariableManager().performStringSubstitution()

without much luck so far - it works though for e.g. workspace_loc and other Eclipse dynamic variables.
I would like to avoid resorting to internal APIs if possible.

Thank you!
