Problem with RPATH setting in executable built as a vcpkg port

Code
1

When I try to debug my executable on macOS and a related executable that was build as vcpkg port, I get:

dyld[68115]: Library not loaded: @rpath/QtXml.framework/Versions/A/QtXml
  Referenced from: <877DDE33-BED7-34DF-A34D-AC7AD5B93D25> /Users/amonra/.vs/DSS/build/DeepSkyStacker/DeepSkyStacker.app/Contents/MacOS/uchmviewer
  Reason: tried: '/Users/amonra/.vs/DSS/build/DeepSkyStacker/DeepSkyStacker.app/Contents/MacOS/../../lib/QtXml.framework/Versions/A/QtXml' (no such file), '/Users/amonra/.vs/DSS/build/DeepSkyStacker/DeepSkyStacker.app/Contents/MacOS/../../lib/QtXml.framework/Versions/A/QtXml' (no such file)

The deployment did copy the QtXml stuff:

which makes me suspect that RPATH is not set “right”.

The portfile.cmake contains:

Oddly If I run uchmviewer from DeepSkyStacker.app/Contents/MacOS it runs without problems!

Either way, I managed to resolve this by adding:

set(CMAKE_INSTALL_RPATH "@executable_path/../Frameworks")
set(VCPKG_FIXUP_MACHO_RPATH OFF)

to portfile.cmake
