Having done some more tests, it looks like when searching the '=' to
add the type information to the option is doing a search from the back
of the string:

   % cmake "-DCMAKE_CXX_FLAGS=-a -one=1 -two=2" ..
   ...
   % grep CXX_FLAGS= CMakeCache.txt
   CMAKE_CXX_FLAGS=-a -one=1 -two:UNINITIALIZED=2

Cheers,
