Thanks @ddcc for checking on `version.h`, I meant to do so but got side-tracked
with other items today.
I think your suggestion is a good compromise, possibly something like the
following as pseudo-code:
if z3_version.h:
use_regex_parsed_version
if version_not_valid and z3_executable:
use_z3_execution output_version
if version_not_valid z3_include_dir:
try_mikhail.ramalho_runtime_check
if version_not_valid:
warning "Z3 is not installed correctly or too old to detect its version"
version = 0.0.0
