Subject: [PATCH] cmake: replace check_library_exists by
 check_cxx_symbol_exists (#991)

As per https://gitlab.kitware.com/cmake/cmake/-/issues/18121,
check_library_exists cannot not determine the availability of a symbol
in a static library. Switch to check_cxx_symbol_exists to avoid
incorrectly detecting the presence of dbghelp.
