v2.3.0

This release changes the include paths provided by our CMake and pkg-config integration. The proper include path for the single-header when using one of the above is now <catch2/catch.hpp>. This change also necessitated changes to paths inside the repository, so that the single-header version is now at single_include/catch2/catch.hpp, rather than single_include/catch.hpp.

Fixes

• Fixed Objective-C++ build
• -Wunused-variable suppression no longer leaks from Catch's header under Clang
• Implementation of the experimental new output capture can now be disabled (#1335)
  • This allows building Catch2 on platforms that do not provide things like dup or tmpfile.
• The JUnit and XML reporters will no longer skip over successful tests when running without -s (#1264, #1267, #1310)
  • See improvements for more details

Improvements

• pkg-config and CMake integration has been rewritten
  • If you use them, the new include path is #include <catch2/catch.hpp>
  • CMake installation now also installs scripts from contrib/
  • For details see the new documentation
• Reporters now have a new customization point, ReporterPreferences::shouldReportAllAssertions
  • When this is set to false and the tests are run without -s, passing assertions are not sent to the reporter.
  • Defaults to false.
• Added DYNAMIC_SECTION, a section variant that constructs its name using stream
  • This means that you can do DYNAMIC_SECTION("For X := " << x).
