I just tried with CMake 1.6.7 and the following works:

PROJECT(foo)
SET(MY_BUILD_TYPE RELEASE CACHE STRING "Debug/Release")
SET(CMAKE_BUILD_TYPE ${MY_BUILD_TYPE} CACHE STATIC "see MY_BUILD_TYPE")

And if I look in the cache, things are set as expected:
$ grep BUILD_TYPE CMakeCache.txt
//see MY_BUILD_TYPE
CMAKE_BUILD_TYPE:STATIC=RELEASE
MY_BUILD_TYPE:STRING=RELEASE

What do you mean by "cannot resolve it"?
