cmake minimum version

latepaul · 10-05-2014, 12:35 PM

I just pulled my Sigil source tree up to the latest git version and re-built. It compiled happily on my Mint 17 machine, once I'd changed the minimum CMake version to 2.8 from 3.0.

As I said it built OK but I guess I wanted to check whether there was a specific reason for the change and whether or not 3.0 features are likely to be needed in the near future.

The change is for two reasons. 1) I'm using cmake 3.0 so I now building with at least that version will work. 2) I'm using the cmake 3.0 docs so I know all functions are used with it. I'm not willing to take the time to cross reference every feature to other cmake versions to determine the minimum possible version.

Also, some features of camke 3.0 are used. such as setting policies. Older version will ignore that. That said I'm not restricting Sigil to using older versions of cmake. If there is a feature in the docs that I want to use and it requires a newer version then it will be used.

Thanks for the response. I just wanted to check. I can always upgrade my version of cmake if/when I need to.
