@fgaz fgaz changed the title cmake: fix risc-v build due to missing atomic ops cmake: fix risc-v build failure Nov 20, 2023
riscv64 is failing due to missing atomic ops in gcc 12.
This commit works around the problem by linking against libatomic.

It can be reverted when we switch to gcc 13 (NixOS#268097)
