# cmake>=4.0 is required: CMake 3.x writes the full target name into the
# file-API reply filename, and MLIR's mlir_generate_type_stubs() builds a
# 283-char target name by joining DEPENDS_TARGETS. That overflows NAME_MAX
# (255), so scikit-build-core fails with ENAMETOOLONG while reading the
# reply. CMake 4.0.0 truncates the name and relies on the trailing hash.
