Try deleting the “build” directory and try again - sometimes Cmake gets confused (or the dependencies aren’t quite right, or both). You might want to update to the latest GitHub sources (9.3.7), although the `utf8proc` package hasn’t changed in a long time. Also: which OS, compiler are you using? (Although this probably won’t make a difference) ```prolog lsb_release -a uname -a gcc --version ``` ---

In theory you should be able to hack around it by first running ``` make utf8proc ``` and then run the normal make. Or, run the above after trapping the failure and run `make` again.
