   git checkout v28.0 ubuntu 18.04 cmake version 3.10.2 gcc version 10.3.0 g++ version 10.3.0

   To learn more about the minimum required dependencies, please refer to https://github.com/bitcoin/bitcoin/blob/28.x/doc/dependencies.md

   My recommendation would be to try to dist-upgrade your Ubuntu, as Ubuntu 18.04 hit end of standard support more than two years ago, according to https://wiki.ubuntu.com/ReleaseTeam

   cmake version 3.10.2

   This CMake version does not understand the -S and -B command line options, which were introduced in the version 3.13. @techy2

   You can download CMake 3.22 or newer, which is required for the main build system on the master branch, from https://cmake.org/download/.
