[cmake-developers] Processing export() at generate-time

[Stephen Kelly]

Hello,

I pushed a export-at-generate-time topic to my clone. It changes the 
behavior of export() to be executed at generate-time by default, unless the 
result is include()d (policy CMP0024).

This is needed to be able to have multiple dependent export sets in the 
build directory. I make use of that in my clone of the boost-cmake repo:

 https://github.com/steveire/BoostCMake/commits/master

Any comments on this? Can I merge it to next?

Thanks,

Steve.
