Only failing on Linux/OSX, probably because of the case sensitive filesystem:

CMake Error at scripts/cmake/vcpkg_fixup_cmake_targets.cmake:45 (message):
  
  '/home/vcpkg/myagent/_work/5/s/packages/libgeotiff_x64-linux/debug/share/GeoTIFF'
  does not exist.

This seems to be working now.

The reason for ❌ is that vxl and openjpeg were also built in the last CI run, and this two ports are mutually exclusive (vxl fails in the presence of openjpeg).

I'll delete the tombstone for vxl and rerun the tests, they should all pass without issues.

I think you faced the same issue with vxl in a different PR, so that one is also probably OK.

✔️ at last.

Thanks @Neumann-A
