Import the external package

You can import catch2 as usual with PID. In the root CMakelists.txt file of your package, after the package declaration you have to write something like:

PID_Dependency(catch2)

It will try to install last version of this external package.

If you want a specific version (recommended), for instance the currently last released version:

PID_Dependency(catch2 VERSION 2.13)

In the CMakeLists.txt files of libraries exporting the dependency :
