In theory, it should be around 2G for 32-bit build of CMake.
In practice, I bet you'll run into the beginnings of performance issues if
you start to have strings that are 10s or 100s of megabytes large.
There's no hard-coded or stack-based limits in CMake that I'm aware of -- it
should be simply based on how much memory CMake can allocate... so:
hopefully, larger than anything you can throw at it... :-)
