So you would recommend checking the generator over setting 
CMAKE_CONFIGURATION_TYPES to CMAKE_BUILD_TYPE initially ?

This is what I was about to do:

if (NOT CMAKE_CONFIGURATION_TYPES AND NOT CMAKE_BUILD_TYPE)
   set(CMAKE_BUILD_TYPE RelWithDebInfo)
   set(CMAKE_CONFIGURATION_TYPES ${CMAKE_CONFIGURATION_TYPES}  
                                 ${CMAKE_BUILD_TYPE} )
endif (NOT CMAKE_CONFIGURATION_TYPES AND NOT CMAKE_BUILD_TYPE)
