[cmake-developers] [vc12/idl] output directory problem

[Tim Blechmann]

hi all,

i'm having troubles with the midl compiler of generated msvc2013 project
files: the generated projects contain a hardcoded output directory:
$(IntDir). however having this property, the midl call fails for me. if
i remove this property, or replace it with $(ProjectDir)/$(IntDir) it
compiles fine.

attached patch resolves this issue for me, though i'm not sure if this
is a good solution in general. also, have to add this include directory:
"${CMAKE_CURRENT_BINARY_DIR}/MyProject.dir/${CMAKE_CFG_INTDIR}"

i'm not an expert on msvc toolchains, so it would be great if someone
could review this patch.

thanks,
tim
