Appreciate your help.
Thanks.

Hi there!

You're missing a dependency: utfcpp. On Debian/Ubuntu this is available as libutfcpp-dev, not sure about Fedora, though. It should be fairly easy to install even without a pre-built package.

Your other alternative is to just use the pre-built binaries from the Releases page.

Feel free to reopen the issue if you still have problems.

Should this be added to the CMake files so that a more relevant error is given and the version is checked?

Possibly. I don't think there's any way to perform a version check for utfcpp, though. Happy to accept a PR :)

[tpwrules]

Ah, I assumed the utf8cpp shipped with a .pc file in which case this would be easy, but evidently not.

[mhx]

Nah, it comes with a (pretty much useless) CMake config, but that's it. As far as I can tell, even the headers themselves don't have any version information.

I have version 4.0.1 installed and CMake can't find it for me.

Yeah, sorry, the utfcpp header files were moved to a different install location with the 4.x releases. There's a bug report, but that got closed without the actual issue being fixed. I've just sent a pull request. Until then, can you downgrade to a 3.x version of utfcpp?
