I agree. My build system will actually have a command-line option to reverse the dependency resolution. Instead of building a given target, updating its dependencies as necessary, it will build the default target(s), marking the files given on the command-line as "changed" and resolving dependents up to the default target(s). This will mean that building the "current file" will be a simple command-line switch that can be part of the file generated for that IDE. But yes, I'm going to put in a lot of work to make IDE's work as smoothly as possible.
