Subject: [PATCH 08/32] Revert "node/convert: relax the check for string_view
 (#1222)" (#1225)

This reverts commit 6262201182a0ee357d8a456e6d1a8e5984e4c6dd.

in 62622011, we wanted address the needs to use the `string_view`
converter in C++98, but that requirement was based on wrong
preconditions. `std::string_view` was introduced in C++17, and
popular standard libraries like libstdc++ and libc++ both provide
`std::string_view` when the source is built with C++17.

furthermore 62622011 is buggy. because it uses `<version>` to tell
the feature set provided by the standard library. but `<version>`
is a part of C++20. so this defeats the purpose of the change of
62622011.

Fixes #1223

Subject: [PATCH 09/32] CI: test with supported C++ standards  (#1226)

* CI: test with supported C++ standards

let's test with the supported standards for better coverage.
C++23 standard was just out, but the support on the toolchain is
not quite ready yet. so let's leave it for a future change.

Signed-off-by: Kefu Chai <tchaikov@gmail.com>

* CI: drop redundant Build step

"Build Tests" is strictly a superset of "Build". in addition to
the library, the former builds the tests also. both these
steps share the same set of command line arguments. by removing
"Build" step, we don't lose anything regarding the test coverage
and information for further investigation if the build fails.

Subject: [PATCH 14/32] Hide uninstall target unless YAML_CPP_INSTALL is set,
 and allow it to be disabled by YAML_CPP_DISABLE_UNINSTALL

add_custom_target uninstall causes a clash with the same target in rtmidi (https://github.com/thestk/rtmidi).
"add_custom_target cannot create target "uninstall" because another target with the same name already exists.  The existing target is a custom target created in source directory"

Adds new option YAML_CPP_DISABLE_UNINSTALL

fixes #1151

Subject: [PATCH 15/32] CMake: Fixes for generated config (#1212)

* CMake: Add option to set the package install dir.

* CMake: Fix generated config.

- `YAML_CPP_SHARED_LIBS_BUILT` should not be set with a `PATH_VAR` as it
would always evaluate to true.
- `YAML_CPP_LIBRARIES` should used the exported target name including
the namespace, but `check_required_components` shouldn't.
- Use `CMAKE_CURRENT_LIST_DIR` to find the target file, instead of a
`PATH_VAR`. Package managers such as vcpkg move CMake configs after
installing.

* CI: Test the generated CMake package.

* CMake: Create add a deprecated yaml-cpp target.

This target is meant to provide compatibility with versions prior to
0.8.0.

* CMake: mark the yaml-cpp target as IMPORTED.

Subject: [PATCH 19/32] Add CMake option YAML_USE_SYSTEM_GTEST to use system
 googletest if available. (#1035)

There is no need to use the embedded gtest code copy in Linux systems, if they already provide the googletest framework system-wide.
Search for it, and fallback to the embedded one if the system one is not detected.

This patch has been also contributed by Simon Quigley <tsimonq2@debian.org>

Protect from regressions due to use of undefined or

pointers.

This only has effect on platforms with the GNU standard C++ library.
