   Right, the problem is the Starting 4.0, Hexagon SDK supports v68, so v68 
libraries are also included in QHL_HVX libs. Excluding just the ones not 
supported for v68 when we mention a lower architecture is a problem because the 
exact files that need to be excluded changes with each Hexagon SDK release. The 
best way is to just use Hexagon SDK 3.5 which is the last version that does not 
have v68 support and so it should work without any change. Or the other option 
is to pass `USE_HEXAGON_QHL=OFF` in your cmake command
