I think there are two minor bugs in current compilation file (compile.bat) at https://github.com/neroist/webview/blob/main/examples/example_application/windows/compile.bat
:: nim c -d:useRC --cc:vcc main.nim
:: nim c -d:usedRC --cc:vcc main.nim # as usedRC in main.nim file
# windres -o build/resources.res -i resources.rc
windres -o build/resources.o -i resources.rc
It worked for me with above suggestions, just putting it here in case somebody faces the same problem!
Before recent commit it was correctly coded as "resources.o" .
Thanks for making it easier to use webview from Nim !
