+Clang attempts to guess file names based on the OS and distro (yes!),
+but unfortunately, that doesn't work for us.
+
+This patch makes it easy to insert libc's $libdir so that Clang passes the
+correct absolute file name of crt1.o etc. to 'ld'.  It also disables all
+the distro-specific stuff and removes the hard-coded FHS directory names
+to make sure Clang also works on non-GuixSD systems.

+Subject: [PATCH] Fix qt5_make_output_file macro for paths containing dots
+
+Commit 89bd5a7e broke CMake projects that use dots in their build
+paths, because the used regular expression matches the directory part
+of the path as well.
+
+The regex wants to achieve the same as get_filename_component(...
+NAME_WLE) which is available since CMake 3.14. Re-implement the
+NAME_WLE functionality for older CMake versions by using multiple
+get_filename_component calls.
+
+Fixes: QTBUG-81715
