MySQL workbench build issue on OpenSuSE 15.5 (no replies)

I am building MySQL_Workbench from source on OpenSuSE Leap 15.5

I have overcome lots of dependencies and am now at the point where is says

Workbench required iodbc or Unixodbc, none was found, CMake will exit.

However, both iodbc and unixiodbc are installed in the system.

I'm thinking this might just need a symlink but cannot figure out where.

Any help appreciated
Thanks
Nigel
