Instead respect what the toolchain default is (or what the user sets via CMAKE_CXX_FLAGS). This fixes builds with libcxx, with mingw toolchains targeting msvcrt.dll, after 5d8be4c036aa5ce4a94f1f37a9155d5c877e23db; after that commit, the libcxx public headers reference symbols such as iswspace_l, which are unavailable when targeting msvcrt.dll on older versions of Windows (it's only available in msvcrt.dll since Windows Vista).
