Changing where a port generated executable looks for libs

[perdrix52]

On macOS I generate a port for uchmviewer. portfile.cmake looks like:

vcpkg_check_linkage(ONLY_STATIC_LIBRARY)

vcpkg_from_github(
    OUT_SOURCE_PATH SOURCE_PATH
    REPO deepskystacker/uChmViewer
	REF d073ff24655bb28c026fe001a30a8408910f49f8
    SHA512 89ae5cd77ab8415f62c94f1baf42a859d6d77b1059c6453098fa801799a794f02e096ac78dd1ad69ac865be662ac95e6c6018486c95c42e4ea3f62c2aff882d1
    HEAD_REF master
)

set(QTDIR $ENV{QTDIR})
set(CMAKE_PREFIX_PATH ${QTDIR}) 
set(ENV{QT_DIR} ${QTDIR})
set(ENV{Qt6_DIR} ${QTDIR})

set(CMAKE_INSTALL_RPATH $ORIGIN)

set(CMAKE_AUTOMOC ON)

set (options
	"-DUSE_WEBENGINE=ON "
	"-DUSE_MACOS_BUNDLE=OFF "
	"-DUSE_GETTEXT=OFF "
	"-DIS_VCPKG_BUILD=ON "
#	"-DUSE_STATIC_CHMLIB=ON "
	"-DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=13.4 "
)

message ( "****************************************************************" )
message ( "EV QTDIR: " ${QTDIR})
message ( "Setting build options: " ${options} )
message ( "****************************************************************" )

vcpkg_cmake_configure(
    SOURCE_PATH "${SOURCE_PATH}"
	OPTIONS ${options}
)

vcpkg_cmake_install()

vcpkg_fixup_pkgconfig()

file(REMOVE_RECURSE "${CURRENT_PACKAGES_DIR}/debug/include")

vcpkg_copy_tools(
        TOOL_NAMES uchmviewer
        AUTO_CLEAN
)
		
vcpkg_install_copyright( FILE_LIST "${SOURCE_PATH}/COPYING" )

When trying to debug 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)

otool -l shows me:

Load command 46
          cmd LC_RPATH
      cmdsize 40
         path @loader_path/../../lib (offset 12)

which I think is causing the problem.

How can I fix this in my port file?

Thanks
David

I added: set(CMAKE_INSTALL_RPATH "@executable_path/../Frameworks") to the port file
but when vcpkg built it, it said:

1> [CMake] -- Adjusted RPATH of '/Users/amonra/vcpkg/packages/uchmviewer_arm64-osx/tools/uchmviewer/uchmviewer' to '@loader_path/../../lib'

I specifically DON'T want that..
