package containing icu-config

[Mick Bert <MickBert@posteo.net>]

Trying to compile a software, the configure fails complaining for 
missing icu-config. I have already installed icu-devtools and 
libicu-dev. Which package should I install?

Are there a way to query which package contains a particular file (maybe 
through apt-get or apt-cache, or even a service on the web)?
