Where do native libraries for a web app go so that that Resin will load them?
The JVM will load libraries from the LD_LIBRARY_PATH or LD_LIBRARY_PATH or DYLD_LIBRARY_PATH.
RESIN_HOME/libexec or RESIN_HOME/libexec64 (depending on OS) will be added to Resin's environment automatically.
Checking what's being set for these can be done with passing --verbose flag to bin/resinctl.
