Replace 4 hardcoded `perl` invocations with `${PERL_EXECUTABLE}` from
find_package(Perl) so builds work when perl isn't in PATH or the wrong
perl would be found (NixOS, custom installs, Homebrew vs system).
Also: fix ZMCONFGEN_RESULT variable case mismatch in error message,
remove deprecated IMMEDIATE keyword from configure_file(), bump
cmake_minimum_required from 3.5 to 3.12 (C++17 requires 3.9+), and
remove dead C++11 fallback for CMake < 3.8 in ConfigureBaseTargets.

- Add optional libunwind support for better stack traces on ARM
(glibc's backtrace() doesn't work well on ARM due to missing
frame pointers)
- Fix misleading signal info: si_pid/si_uid/si_status are only
valid for SIGCHLD, not for SIGSEGV/SIGBUS - they were showing
garbage values (the fault address misinterpreted as PID)
- Add human-readable fault descriptions for SIGSEGV, SIGBUS,
SIGFPE, and SIGILL signals
- Use clearer terminology in error messages
To enable libunwind on ARM: apt install libunwind-dev

The manpage compression metadata include the true build time (and not
SOURCE_DATE_EPOCH like the manpages themselves). Excluding the build time
allows the manpage to be build reproducibly.

Improves detection across different platforms (esp. FreeBSD) since system paths are automatically taken into account (this is in contrast to check_include_file).
Introduce the -DZM_JWT_BACKEND CMake option through which the JWT backend can be selected.
Supported values: jwt_cpp (default; in-tree) and libjwt
When libjwt is chosen ZM_CRYPTO_BACKEND is taken into account to select the corresponding flavour of libjwt.
The zm-dependency-interface target sets compiler flags in a way suitable for external dependencies.
This means mainly to disable compile warnings since they concern upstream and not us.
zm-compile-option-interface:
Use to set various compiler/linker flags
zm-feature-interface:
Use to set required compiler features.
See https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html
zm-warning-interface:
Use to set compiler warning flags. If need be a zm-no-warning-interface can be added which suppresses all warning for targets linked against it. Useful for in-tree dependencies from which we don't want compiler warnings.
zm-core-interface:
That's the interface one should normally link against to get all the options.
