Need to be able to look for a source using any type of case

I am a bit unsure of the syntax, this command works as long as the source is exactly as this, but ideally I want it to search for any type of case as path can be LogFiles or Logfiles

if [source] =~ "C:\Windows\System32\LogFiles\Firewall*.log"

Advice is greatly appreciated.

have added a mutate before the source and changed slightly what I am monitoring, works with no issues
mutate {
lowercase => [ "source" ]
}
