Finish the Meson changes from #4452: - Offer all eight options that change the CMake target, named like the CMake options without the JSON_ prefix. MultipleHeaders defaults to false so that existing Meson users keep the single header. - Add a compile definition only for an option that differs from its default, exactly as target_compile_definitions does. Before, the GlobalUDLs and ImplicitConversions definitions were inverted and were also added in the default configuration. - Keep the nlohmann_json_multiple_headers dependency that earlier versions of meson.build provided. - Put the definitions into the pkg-config file and the Meson-generated nlohmann_jsonTargets.cmake, and install the pkg-config file into <datadir>/pkgconfig like CMake does. - Ship meson_options.txt in include.zip, since meson.build now reads options and the zip is documented as a Meson subproject.

# CMake installations generate this file with install(EXPORT ...). Meson cannot

# do that, but as the library is header-only, the target only needs an include

# directory, the C++ standard, and the compile definitions of the options that
|
|
# differ from their defaults. Paths are computed relative to this file so that
|
|
# the installation can be relocated (e.g., into a sysroot).
