At my company we have a large C++ project with multiple features that can be enabled or disabled with various preprocessor definitions.

If we were to enumerate each of the possible preprocessor/feature combinations in a list of Project Configurations, we’d have ourselves quite an extensive list (not to mention long configuration names)!

Is there a plug-in – or some other unknown feature – which can display a prompt when a user initiates a build, such that the user can check/uncheck a list of configurable features, in order to enable or disable the preprocessor definitions?

Something like this would be awesome:

    You could create a simple application which will produce a header file with defines

    #ifndef __GEN_CONFIG__
#define __GEN_CONFIG__

#undef  LOGGING
#define LOGGING 1 // for example

#undef  FEATURE_A
#define FEATURE_A 0

#endif

    this header can then be included in the project.

    The application/dialog can be executed as a Visual Studio Pre-Build event, to ensure that the header file is updated right before compilation.
