GitHub runners bundle a number of unnecessary packages, including a newer version of CMake. Runners prefer using bundled libraries and binaries over explicitly installed packages by default.
The CI build environment should match the expected environment (e.g. Ubuntu 20.04) as closely as possible, in order to mitigate unintended build system regressions.
