Highs.h is installed at /usr/local/include/highs/Highs.h by coin-or-highs-1.6.0

Version: 2.7.6

This is an error in newer versions of Highs: ERGO-Code/HiGHS#1308

A workaround has been added in the current develop versions of MiniZinc (and the releases will now uses dlopen to load the libraries rather than including them in the executable)

Just a note, if you build HiGHS with -DFAST_BUILD=OFF then it should actually work as well.
