Using branch point for count since last change since we don't
have questions answered on tags yet.
Removed unused CMake files.
Restructured CMake to use the cache rather than only commandline
and be ccmake & cmake-gui friendly.
Dependency search paths are added for the Repo tree layout.
Search paths still needed for install paths.
Simplified packaging. hsa-ext-rocr-dev package and contents now
build from the package CMake rather than being 3 separate projects.
Not applying new version number or new install paths!
