# Since we bring along our own version of Catch2, we prefix the target with the # project name. Alternatively we could check whether Catch2::Catch2 is already # available and use that one instead of our own via `add_library(mylib_Catch2 # ALIAS Catch2::Catch2)`. add_library(mylib_Catch2 INTERFACE) target_include_directories(mylib_Catch2 INTERFACE .)
