I added the following notation to the Useful Variables page of the wiki:

"Note that CMAKE_BUILD_TYPE is not initialized with a readable value
at configuration time. This is because the user is free to select a
build type at build time. Use CMAKE_CFG_INTDIR if you need a variable
that evalulates to the correct buld time directory."
I am wondering if this behavior should be considered a bug. Even if
not, it's definitely inconsistent with user expectations. I'm not
sure my documentation above is wholly correct, but it's a 1st stab at
alleviating confusion.
I am not sure the wiki is exactly correct....
Basically, there are two types of generators, single build type per
build tree, and multi- build type per tree. The variables that are
useful for that are here:
CMAKE_BUILD_TYPE is used by makefile generators or any future generator
that supports one build type per build tree. The default value is now
Debug.
CMAKE_CFG_INTDIR is set by generators like MSVC IDE and Xcode that
support building more than one build type per build tree.
CMAKE_CONFIGURATION_TYPES is set to the list of available build types
for the current generator (empty for makefiles, and Debug, Release, etc
for IDE)
