[Cmake] map insert

[Cross, Geoff (CRD)]

In cmMakefile->AddDefinition you have the following

m_Definitions.insert(DefinitionMap::value_type(name, value))

The result of this is that if I do a

SET( something "YES" )
SET( something "NO" )

the result is something=YES and not something=NO as I would normally expect: is this deliberate, or
can I correct this?

Geoff.
