cmake: Error on invalid CMAKE_BUILD_TYPE

Browse Source 
Apparently if you make a typo in the argument to CMAKE_BUILD_TYPE,
cmake silently accepts this but doesn't apply any particular build
type to your build. This means you get a build that doesn't really
make any sense - it's sort of a debug build with asserts disabled.

Error out instead.
