Version 2.0.0

This release adds the option to install the tracker an imported target in CMake projects. This enables you to use find_package to import the installed project in your CMakeLists.txt. The tracker now also recognises dependencies (e.g., libcurl) installed through Conan.

The minimum CMake version was raised from 3.14 to 3.15. Also the SQLite3 and libcurl dependencies are now private within the project and libcurl is no longer used on macOS.

Big thanks for this release goes to @tamaskenezlego who contributed most of the changes!

Version 1.0.0

This is the first stable release of the tracker and adds the tracker to the list of our maintained trackers!

The release brings updates to the API and introduces a Snowplow class for easier initialization and management of one or more trackers. A new tracker can now be initialized with a single line of code, e.g., auto tracker = Snowplow::create_tracker("ns", "https://collector.com", POST, "sp.db");.

Support for the cmake build system was also introduced. This enables the package to be imported into other cmake projects. The library can be still be installed without using cmake by copying source files from the include folder.

Other changes include support for storing HTTP cookies in collector requests, adopting the version 1.0.2 of the client_session schema for session context entities with eventIndex and firstEventTimestamp properties, new API docs, and integration tests.
