catch_discover_tests needs to support relative paths #3051
Description
Description
catch_discover_tests needs to support relative paths. currently it populates _include.cmake files with absolute paths for DISCOVERY_MODE PRE_TEST.
Making them relative allows user to seperate the build and execution on different platforms/systems. This allows portability of test artifacts.
Additional context
https://github.com/catchorg/Catch2/blob/devel/extras/Catch.cmake#L263 -
TEST_EXECUTABLE" " [==[" "$<TARGET_FILE:${TARGET}>" "]==]" "\n"
$<TARGET_FILE: ----> populates the absolute path during the build time. Which does not exist at execution runtime
Need to create a flag USE_RELATIVE_PATHS to allow user to pass relative paths instead of having them populated at build time
