[CMake] cmake documentation incomplete

[Vania Joloboff]

Thanks Nicholas,

Then if I run cmake from a shell script in working directory pwd
(and I do not want to cd)
can I tell cmake the first time to take the source
in path-to-source and do the build in path-to-build ?

I have read there is an undocumented option -B to do this ?
