* Add zstd support
* Add zstd to CI tests
* Use use zstd cmake target instead of ZSTD. Use cmake variable for found packages
* Add missing comment for HTTPLIB_REQUIRE_ZSTD
* Fix test.yaml rebase error
* Use zstd::libzstd target
* Add include and library paths to ZSTD args
* Run clang-format
* Add zstd to httplibConfig.cmake.in
* Move httplibConfig.cmake.in to cmake dir
Just makes more sense to put it there I suppose.
* Cmake install README & License
Seems to make sense since you might already do this as a package
manager, or an end user might want them anyways.
The locations are just based on standard Linux locations using
GNUInstallDirs, so it should be sane on other machines too.
