I definitely did cache it (without that it has no effect).  In my
super-simple test case (which looks like yours) it works fine.

But in my real project when I do it this way, I do see all the
configuration types listed in the CMakeCache.txt file, but I also get
all those error messages about "internal CMake variable not set" for
each of the MINSIZEREL build type variables.  I double-checked and there
are no errors for the other types, including RelWithDebInfo.

This behaves identically with 2.8.11-rc4 BTW.
