You're not bound to these particular variables. CMake scripts can use 
environment varables and command line switches, which covers different 
configurations quite well. Just define a couple of your configuration 
variables for different targets and be done with it. You can even create your 
own CMake module that handles all the configuration specifics you have.

I think CMake documentation issues are not relevant to Boost per se.
