A test runner already has a --durations option to print durations.
However, this isn't entirely satisfactory.
When there are many tests, this produces output spam which makes it hard
to find the test failure output. Nevertheless, it is helpful to be
informed of tests which are unusually slow.
Therefore, introduce a new option --min-duration that causes all
durations above a certain threshold to be printed. This allows slow
tests to be visible without mentioning every test.
--- Fixes ---
* Vector matchers now support initializer list literals better
--- Improvements ---
* Added support for `^` (bitwise xor) to `CHECK` and `REQUIRE`
--- Improvements ---
* Running tests in random order (`--order rand`) has been reworked significantly (#1908)
* Given same seed, all platforms now produce the same order
* Given same seed, the relative order of tests does not change if you select only a subset of them
* Vector matchers support custom allocators (#1909)
* `|` and `&` (bitwise or and bitwise and) are now supported in `CHECK` and `REQUIRE`
* The resulting type must be convertible to `bool`
--- Fixes ---
* Fixed computation of benchmarking column widths in ConsoleReporter (#1885, #1886)
* Suppressed clang-tidy's `cppcoreguidelines-pro-type-vararg` in assertions (#1901)
* It was a false positive trigered by the new warning support workaround
* Fixed bug in test specification parser handling of OR'd patterns using escaping (#1905)
--- Miscellaneous ---
* Worked around IBM XL's codegen bug (#1907)
* It would emit code for _destructors_ of temporaries in an unevaluated context
* Improved detection of stdlib's support for `std::uncaught_exceptions` (#1911)
This also goes for pkg-config installed by our CMake installation.
This includes
* Updating CMake version on Travis
* Adding a `Catch2` subfolder to the `single_include/` folder to
provide this include path both _inside_ the repository, and _outside_.
* Updated examples to build with the new paths
* Other general CMake cleanup
