Bug#1054624: endless-sky: Build-Depend on cmake (>= 3.21)

[David (Plasma) Paul]

Source: endless-sky
Version: 0.10.2-1
Severity: wishlist

Dear Maintainer,

Please modify endless-sky's Build-Depends on 'cmake' to
'cmake (>= 3.21)' to match the cmake_minimum_required() function call
in the CMakeLists.txt file and to aid in build dependency resolution
during backporting.

Thanks,
