This is a SlackBuild for the plugin collection included in the Psi+
source snapshot. 
It targets the SlackBuilds.org Psi+ package. 

OMEMO needs signal-protocol-c:

  WITH_OMEMO=YES sh psi-plus-plugins.SlackBuild

OTR needs libotr:

  WITH_OTR=YES sh psi-plus-plugins.SlackBuild

The screenshot plugin needs Qxt, while psimedia and videostatus need 
their respective multimedia dependencies. 
Enable only after their dependencies are installed:

  WITH_SCREENSHOT=YES sh psi-plus-plugins.SlackBuild
  WITH_PSIMEDIA=YES sh psi-plus-plugins.SlackBuild
  WITH_VIDEOSTATUS=YES sh psi-plus-plugins.SlackBuild

FULL=YES enables psimedia and asks CMake to build every plugin.
It is intentionally not the default: it will fail until every optional
build dependency is present.

  FULL=YES sh psi-plus-plugins.SlackBuild

After installing the package, enable plugins in Psi+ through:

  Options -> Plugins
