Interesting. Looks like a bug to me.

What are you actually trying to do? The only thing I can think of is to
split the clause into two separate variables. 

Your CMakeLists would have ${foo1}=${foo2} and then from the command line do cmake -Dfoo1=bar -Dfoo2=baz. Kinda ugly but maybe it unblocks you? The real CMake developers don't check their list mail over the weekend, so you're stuck with me for now :).
