Subject: [PATCH] cmake: Explicitly search for Catch2 version 3
The current CMakeLists block
find_package(Catch2)
if(Catch2_FOUND)
target_link_libraries(test_suite Catch2::Catch2WithMain)
include(CTest)
include(Catch)
catch_discover_tests(test_suite)
endif()
would search for any Catch2 version, but later tries to link against
Catch2 version 3 (Catch2WithMain). This means the block would fail on
systems that have Catch2 version 2 installed, but not Catch2 version
3. Fix that by requesting Catch2 version 3 when invoking
find_package().
