I do not know much about Arduino either,but i can tell you what I have done to succesfully compile and run OPensprinkler on ESP32 module.
Downloaded as you mentioned the zip file for opensprinkler and also the other 3 libraries.
I have put those three libraries under the library folder within Arduino . When trying to compile got same message about creating a folder with name mainarduino ,so I have also put all the opensprinkler files under this new folder (not the other 3 libraries) . Then run the compiler again and this is the log should it help.

BTW, the ESPmodule is ESP WROOM 32 with 9102 usb-serial chip. My Arduino version is 1.8.19
Hope this helps
