An installation overview can be found at this location:
HSA Platforms & Installation · HSAFoundation/HSA-Docs-AMD Wiki · GitHub
Please follow the overview and use the runtime *.deb packages found here
HSA-Runtime-AMD/ubuntu at master · HSAFoundation/HSA-Runtime-AMD · GitHub
to install the HSA Runtime, not the files built in the HSA-Runtime-Reference-Source repository.
The HSA-Runtime-Reference-Source is primarily for reference (as the name implies) and is for advanced users. Less technical folks should stick with the path detailed on the "HSA-Docs-AMD" wiki.
Any specific issue with the documentation on those pages should be opened as an issue.
