+# CMake automatically adds an architecture compatibility check to make sure
+# 32 and 64 bit code is not accidentally mixed. For a header-only library this
+# is not required. The check can be disabled by temporarily unsetting
+# CMAKE_SIZEOF_VOID_P. In CMake 3.14 and later this can be achieved more cleanly
+# with write_basic_package_version_file(ARCH_INDEPENDENT).
+# TODO: Use this once a newer CMake can be required.
