Set `_CATCH_DISCOVER_TESTS_SCRIPT` helper variable globally. Otherwise in a
scoped call (like `add_subdirectory()`) the variable gets lost. This lost
variable results in a post build error with not much information to lead to the
root of the problem.
This enables the usage of the helper script with the following example structure
- CMakeLists.txt (project root with `add_subdirectory(external/catch2)`
- external/catch2
- CMakeLists.txt (contents listed below)
- contrib/Catch.cmake
- contrib/CatchAddTests.cmake
- catch2/catch.hpp
- tests
- CMakeLists.txt (add tests with `catch_discover_tests(${PROJECT_NAME})`)
contents of project specific helper `external/catch2/CMakeLists.txt`
```cmake
cmake_minimum_required (VERSION 3.1...${CMAKE_VERSION})
project(Catch2 LANGUAGES CXX VERSION 2.13.3)
add_library(Catch2 INTERFACE)
target_include_directories(Catch2
INTERFACE
$<BUILD_INTERFACE:${CMAKE_CURRENT_LIST_DIR}>
)
# provide a namespaced alias for clients to 'link' against if catch is included as a sub-project
add_library(Catch2::Catch2 ALIAS Catch2)
include(contrib/Catch.cmake)
```

Catch2 is released!
If you've been using an earlier version of Catch, please see the Breaking Changes section of the release notes before moving to Catch2. You might also like to read this blog post for more details.
What's the Catch?
Catch2 is a multi-paradigm test framework for C++. which also supports Objective-C (and maybe C). It is primarily distributed as a single header file, although certain extensions may require additional headers.
How to use it
This documentation comprises these three parts:
- Why do we need yet another C++ Test Framework?
