MakeMaker was only used to copy .pm files — no XS compilation, no binary
linking, no dependency resolution. Its hardcoded "Makefile" output name
conflicts with cmake's generated Makefile for in-source builds, and using
FIRST_MAKEFILE=MakefilePerl causes thousands of "uninitialized value"
warnings because MM.pm stats the wrong file.
Replace with native CMake install(DIRECTORY ... FILES_MATCHING PATTERN
"*.pm") directives. Perl module install path is auto-detected at configure
time via `perl -MConfig` (vendorlib on Linux, sitelib on FreeBSD),
overridable with -DZM_PERL_INSTALL_PATH=<path>.
What's removed:
- ExtUtils::MakeMaker as build dependency
- Three perl+make subprocesses at build time (zmperlmodules,
zmonvifmodules, zmonvifproxy build targets)
- ~6000 auto-generated man3 pages from WSDL stubs
- MakeMaker scaffolding: Makefile.PL, MANIFEST, META.yml, Changes,
README, and t/ZoneMinder.t test stub
What's preserved:
- configure_file() for .pm.in templates (same behavior)
- ZM_PERL_SEARCH_PATH (independent mechanism, unchanged)
- Section 8 man pages for .pl scripts (Pod2Man.cmake, unaffected)
- DESTDIR support (CMake install() handles natively)
- Installed file paths (perl -MConfig returns same paths MakeMaker used)
Verified: 3102 .pm files installed, 0 .pm.in files, 0 .3pm man pages,
no @VERSION@ markers in generated files, DESTDIR and user override work.

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.

Also remove expressions form closing tags. They have been made optional a while ago since they make reading rather more difficult.
Add a new CMake option (-DBUILD_MAN) which can be used
to deactivate the man page build steps.
This is especially useful in a development situation where "make all"
is needlessly slowed down by these build steps.
