+# See https://unix.stackexchange.com/a/700599. libQt6Core.so.6 adds a tag that denotes a minimum kernel version required
+# to run it and is set to 3.17.0, above Centos7's 3.10.0. This is why the library was never found even within a 
+# container despite successfully finding other Qt6 libraries. This command removes that tag so Qt6Core will function on 
+# Linux kernel 3.10.0
