// list (and passed as the item metadata %(Filename) expressing the rule
// input filename) into output files at the per-config *build* dir
// ($(IntDir)) each.
//
// IOW, this MIDL section is intended to provide a fully generic syntax
// content suitable for most cases (read: if you get errors, then it's quite
// probable that the error is on your side of the .idl setup).
//
// Also, note that the marked-as-generated _i.c file in the Visual Studio
// generator case needs to be referred to as $(IntDir)\foo_i.c at the
// project's file list, otherwise the compiler-side processing won't pick it
// up (for non-directory form, it ends up looking in project binary dir
// only). Perhaps there's something to be done to make this more automatic
// on the CMake side?
