	<!-- We build with GCC 7 for max compatibility. But this has an ARM ABI breaking change due to
		 fixing a bug introduced in GCC 5.2, specifically triggered by our functions that pass
		 vector iterators.
		 The ABI change implies C++ libraries built with GCC 6 or below will break if called by 7+.
		 You can ignore it if all your libraries are built by GCC 7+, and Lacewing and
		 its OpenSSL dependencies are indeed built with GCC 7+.
		 The warning message was removed in GCC 14.x.
		 This content checks GCC version is 7.x to 13.x, and if so, turns off the warning message.
