Did this, because with 3.0.1, the files
- catch_xmlwriter.cpp
- catch_string_manip.hpp
- catch_test_case_info.hpp
were missing
This led to some obvious and some obscure compile errors when compiling
with g++ 13.2.0 (std c++17 or c++20)
One of these errors being "Elaborated-type-specifier for a scoped enum
must not use the ‘class’ keyword"
Since this is a rather bad experience and debugging it is
time-consuming, I suggest to simply boost the recommended version in the
snippet which is likely copied by new Catch2 users
Introducing a new DISCOVERY_MODE mode option, which provides greater
control over when catch_discover_tests perforsm test discovery.
It has two supported modes:
* POST_BUILD: The default behavior, which adds a POST_BUILD command
to perform test discovery after the test has been built as was
always done so far.
* PRE_TEST: New mode, which delays test discovery until test execution.
The generated include file generates the appropriate CTest files at
runtime and regenerates the CTest files when the executable is
updated.
This mode can be used in build-environments that don't allow for
executing the linked binaries at build-time (like in a
cross-compilation environment).
DISCOVERY_MODE can be controlled in two ways:
1. Setting the DISCOVERY_MODE when calling catch_discover_tests.
2. Setting the global CMAKE_CATCH_DISCOVER_TESTS_DISCOVERY_MODE prior
to calling gtest_discover_tests.
Closes#2493
`FetchContent` doesn't include `contrib` directory as part of `CMAKE_MODULE_PATH`. This results into `include(Catch)` to fail. This patch just updates the documentation describing how to do include the path, so the new users don't have to figure this out themselves.

Parsing C++ with regex in CMake is error prone and regularly leads to silently
dropped (not run) test cases.
Going forward the function `catch_discover_tests` from `contrib/CMake.cmake`
should be used.

* Update cmake-integration.md
CMake related, mainly more modern and provide an executable to be correct

This variable is set to allow the use of the nice ParseAndAddCatchTests script
in the case where a launcher is needed to execute the script.
This is introduced to allow to launch unit tests using mpi. In this case one can
write for instance
set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC})
before calling the ParseAndAddCatchTests function.
This might prove helpful when the package managers either doesn't
have Catch at all, or provides it in obsolete version (Ubuntu 16.04,
I am looking at you).
Closes#1383
