CMake build requirement #4

Closed Pesa closed 5 years ago

Pesa commented 5 years ago

I think the current requirement of cmake >= 3.11 is pretty high. The latest Ubuntu LTS has 3.10.2 (https://packages.ubuntu.com/bionic/cmake), which makes it hard to build this package on Ubuntu, since most people only use LTS releases.

I wonder if it's feasible to slightly lower the requirement to >= 3.10 ?

If you intend to support Raspbian, lower the requirement to cmake 3.7.2 as it's the version packaged by Debian Stretch and used in current Raspbian release.

I think it's possible to lower it to 3.10 because currently we only need the following feature of 3.11:

add_library() and add_executable() commands can now be called without any sources and will not complain as long as sources are added later via the target_sources() command.

But I'm not sure if I can make it to 3.7. I will have a try.

Thanks. You forgot to update the README, it still says "CMake >= 3.11"
