I've spent some time analyzing this, and indeed there of course is a clean way
to isolate this from single-configuration generators' CMAKE_BUILD_TYPE stuff,
e.g. by defining per-configuration settings such as
set_property(TARGET ... COMPILE_DEFINITIONS_MINSIZEREL ...)

**HOWEVER**, well, in fact it's all falling apart after all:

"[CMake] Add configuration support to include_directories()": http://www.mail-archive.com/cmake@cmake.org/msg18270.html

is the #1 reason that a full round-trip .vcproj --> CMakeLists.txt --> .vcproj
will _NOT_ retain all project content satisfactorily
(i.e. we will have to make the hard choice of hard-coding _either_ the Release
_or_ the Debug .vcproj Configuration's AdditionalIncludeDirectories setting
in the resulting converted CMakeLists.txt), since there isn't a
per-configuration include_directories() setup yet
(at least according to that thread's discussion).

Houston...

Hmm, create bug report?
