In other words, I need to define global variables in a package which can
be used across multiple packages. At present the only option I have is
to export the variable in build/conf/local.conf. IMHO, this doesn't feel
like a proper solution (as the variable is my layer specific). Moreover,
I can't change the value of it in one package to be used in other
package(s).

Is there any other way to do this? Please guide me.

Regards
Joshua
