[CMake] adding and removing build configuration types

[ElderOrb]

Hello, cmake.

There are 4 default build configurations defined by cmake: "debug",
"release", "minSizeRel" and "relWithDebInfo". How to remove "minSizeRel"
and "relWithDebInfo" and add "debug unicode" and "release unicode"?
("debug unicode" is just "debug" with -DZ_UNICODE definition, the same
is true for "release unicode")

I tried to play with CMAKE_CONFIGURATION_TYPES, CMAKE_BUILD_TYPE, read
faq and had much googling - all without success.
