This reverts commit 1f5e971f.

See #1306; the previous commit caused an error with -Wpedantic:

yaml-cpp/include/yaml-cpp/emitterstyle.h:13:2: error: extra ‘;’ [-Wpedantic]

Since the original commit was to resolve warnings, reverting and the OP can produce a new one that fixes this issue.

The CMake format target does not use the correct .clang-format file in
out-of-source builds. This instructs CMake to use the project root as
the working directory for running the clang-format command so that it
finds the .clang-format file.

Since `std::string` has to be dynamically constructed and destructed,
it could be accessed before initialization or after destruction in a
multithreaded context. By using constant c-strings instead, we guarantee
that the array will be valid for the whole lifetime of the program. The
use of `constexpr` also enforces this requirement.

I have run clang-format on the file to format my changes according to
CONTRIBUTING.md.

These caused issues when used in a wasm project.

Protect from regressions due to use of undefined or
implementation-specific behavior when using `std::` containers and smart
pointers.

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

Refer to https://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.html.

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.

* 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.

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

node/convert: Enable the template specialization for `std::string_view` properly when the library is compiled by MSVC on Windows. (#1227)

* 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.

* 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.

This reverts commit 62622011.

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
