Note that by just using cleanupCacheDir = TRUE does not help, which I though would do essentially the same thing.

sourceCpp() does this:

    # cleanup the cache dir if requested
    if (cleanupCacheDir)
        cleanupSourceCppCache(cacheDir, context$cppSourcePath, context$buildDirectory)

I think we should try to focus on which if any files are still left behind by
cleanupSourceCppCache() and also remove them.

This ought to be fixable.
