Support cmake config with meson build

[chenrui333]

It looks like the meson build does not create cmake config, which caused some downstream issue.

relates to:

• https://github.com/Homebrew/homebrew-core/pull/133342
• https://github.com/open-source-parsers/jsoncpp/wiki/Building#building-and-testing-with-cmake
• https://github.com/Homebrew/homebrew-core/pull/133345

Can confirm this causes issues: https://github.com/LunarG/VulkanTools/pull/1917

I'm hopeful for a standardized solution in the future (pkg-config has issues on Windows): https://www.youtube.com/watch?v=IwuBZpLUq8Q
