From 33c89f98377cb968b03eb1428af8a74eba9d13ce Mon Sep 17 00:00:00 2001 From: James Hilliard Date: Sun, 29 Jan 2023 21:29:13 -0700 Subject: [PATCH] package/fxdiv: fix build without C++ toolchain The cmake project for fxdiv sets the project language to C and CXX even when only C is required. Add a patch which disables CXX unless required.
