CTest errors when collecting coverage results

Usage
1

When running my CTest dashboard script with coverage flags enabled, it works perfectly for GCC. But for Clang builds, I get output such as:

Command produced error: D:/a/BenBot/BenBot/Builds/clang/libbenbot/resources/CMakeFiles/ben_bot_resources_internal.dir/Debug/__cmrc_ben_bot_resources_internal/intermediate/res/bench.epd.cpp.gcno:version 'B11*', prefer 'B52*'

The build itself produces no warnings/errors, and all tests pass, but CTest exits with code 32.

The coverage flags config is:

if (CMAKE_CXX_COMPILER_ID MATCHES "GNU|Clang")
    get_cmake_property (debug_configs DEBUG_CONFIGURATIONS)

    if (NOT debug_configs)
        set (debug_configs Debug)
    endif ()

    list (JOIN debug_configs "," debug_configs)

    set (config_debug "$<CONFIG:${debug_configs}>")

    add_compile_options ("$<${config_debug}:-g;-O0;--coverage>")
    add_link_options ("$<${config_debug}:--coverage>")

    if (CMAKE_CXX_COMPILER_ID MATCHES "GNU")
        link_libraries (gcov)
    endif ()
endif ()

An example build log is [here](CI (benthevining) · benthevining/BenBot@270d93b · GitHub), and the CDash dashboard is [here](https://my.cdash.org/index.php?project=ben-bot).

Is there something wrong with the coverage flags I’m using? Should I consider using a custom CTest script instead of just ctest -D, so that I can silence the spurious exit code?
