I know this was a major deal when creating the compile-commands.json for other native IDE integrations. I've heard some IDEs just run the build once and inspect the command lines, but our default log level won't show that. I'm not familiar with eclipse project files, but I couldn't really see anything here that addressed this issue. Can you work with the native code in a meaningful way without it?

@erikj79 @magicus Seems like this is the best I can do for now, baseline support for Eclipse should now be present with these final touchups (Environment setup is not fully complete yet, but Eclipse is flexible enough that for most development work, this should not be too problematic). I do plan to refine support for it in the future, since there are still areas for improvement, but at present I think this should be decent enough for the time being
