# This is a workaround for upstream issue: https://gitlab.kitware.com/cmake/cmake/-/issues/22995.
#
# In Clang.cmake, the decision to use single or double hyphen for target and gcc-toolchain
# is made based on CMAKE_${LANG}_COMPILER_VERSION, but CMAKE_ASM_COMPILER_VERSION is empty
# so it picks up single hyphen options, which new clang versions don't recognize.
