Could not find BISON (CMake error)

[ProfTuan]

Just want to mention, I had the following issue when trying to build framework for the first time:

CMake Error at /usr/local/Cellar/cmake/3.21.3_1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find BISON: Found unsuitable version "2.3", but required is at
  least "3.0" 

I was able to rectify it by updating bison brew install bison

afterwards it succeeded when I build the framework.

Thanks for the report. OWL API for iOS was recently updated to use Cowl as the backend for ontology parsing, which requires Flex and Bison to be installed and relatively up to date. This is not reported at all in the docs, so I'll update them accordingly.
