Question: Sharing modules between multiple applications

[leondavi]

As an example, the following directories hierarchy is given:
App1
-- rebar.config
App2
-- rebar.config
SharedModules
-- example1.erl
-- example2.erl

How should I modify rebar.config of both applications to include modules of SharedModules directory and successfully compile release as well (using rlx)?

Clarification:
rebar3 compile and rebar3 release commands outputs should include modules within SharedModules, allowing App1 and App2 importing them.
