 It has been tested with Dymola, but should also work with OpenModelica
 since they use the same compiler under Linux. 
 
+Please note that you have to add the dl library to the compilation if you 
+would like to use NIST REFPROP through the CoolProp interface. For Dymola, 
+you can add "-ldl" to the compilation options in the dsbuild.sh file in 
+/opt/dymola/insert.

 Please follow the developer instructions in `Projects/CompilationHowTo.txt`
+to create your own version of ExternalMedia.
