[cmake-developers] I'm sure this is often asked

Any reason that environment variables can't be used as cmake
variables?  Like of course any cmake variable in a script would
override the environment, but if it's not otherwise found, checking in
the environemnt would make scripts prettier.


set BUILD_TYPE=debug
set BUILD_MONOLITHIC=1
cmake /path/to/source

instead of having to pass -DBUILD_TYPE=debug -DBUILD_MONOLITHIC which
gets strung out all on one line usually.  some longer varaibles might
be -DSACK_INTERSHELL_SDK_ROOT_PATH=$SACK_INTERSHELL_SDK_ROOT_PATH

or appropriate bash/batch syntax as applicable.
