Cmake build: Fine tuning
...
1.) If building with external iconv, remove remnants of libiconv data
created if previousy used internal iconv
2.) Remove the variable HELP from cache to enable subsequent builds.
(Different variable-handling on new cmake (version >= 3.18))
3.) New macro to extract cmake-known-cxx-sts features
4.) Check for CXX11-features only for a subset of possibilities
known by the used cmake

Amend 9c863039: Cmake build: Adapt handling of c++ standards to new Visual C++ 2019

Apparently the use of "/std:c++20" is too new for our sources.

Extend Clang compiler detection to cover Apple CLang
...
CMake 3.0 and above recognize that Apple Clang is a different compiler than upstream Clang and so it gets a different CMAKE_CXX_COMPILER_ID.

Fix MSVC C++11 detection
...
The old version with empty flag did not enter the loop at all, so we have to
use a workaround. Thanks Uwe for testing.

Do not use --std=c++14 for MSVC
...
MSVC does not need a special flag to specify the standard. Using --std=c++14
produces a warning, but compilation succeeds, so the old code did mistakenly
choose --std=c++14 for MSVC.

Fix std::regex detection for older gcc
...
Older gcc versions (e.g. the first one which has usable std::regex: gcc 4.9)
require the --std=c++11 flag to be set. Otherwise std::regex is not made
available. Therefore we need to keep the flag in the loop.
