Since this PR bumps the minimum required CMake version, this should go into a feature release, i.e. VOLK v3.2. |
In cases where we don't cross-compile, we might want to detect if a CPU is 32bit or 64bit. CMake provides functionality for this case starting in CMake 3.10. Let's use it. Ubuntu 20.04 uses CMake 3.16. From the top of my head, this is the oldest supported distribution. Debian buster ships with CMake 3.13. Signed-off-by: Johannes Demel <jdemel@gnuradio.org>
