Installing CMake package config files for MacOS frameworks - macos

Question

I created a versioned MacOS framework with CMake and stumbled over the question where to install the package config files sample-config.cmake, sample-config-version.cmake, sample-exports.cmake, sample-exports-release.cmake.
The framework is versioned so the structure is roughly as follows:
<sample.framework>
|-- Headers # link to Versions/Current/Headers
|-- Resources # link to Versions/Current/Resources
+-- Versions
|-- Current # link to B
+-- B
|-- Headers
+-- Resources
|-- CMake
+-- Info.plist
I use CMakes CMakePackageConfigHelpers macros to generate a package config file from a template sample-config.cmake.in with the content
#PACKAGE_INIT#
include("${CMAKE_CURRENT_LIST_DIR}/sample-export.cmake")
CMake does not mention versioned frameworks and recommends to install the files into the directory Resources/CMake.
I did so by calling
install(FILES "${CMAKE_CURRENT_BINARY_DIR}/sample-config.cmake"
DESTINATION sample.framework/Resources/CMake
COMPONENT development
)
The generated file looks like this:
####### Expanded from #PACKAGE_INIT# by configure_package_config_file() #######
####### Any changes to this file will be overwritten by the next CMake run ####
####### The input file was sample-config.cmake.in ########
get_filename_component(PACKAGE_PREFIX_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../" ABSOLUTE)
macro(set_and_check _var _file)
set(${_var} "${_file}")
if(NOT EXISTS "${_file}")
message(FATAL_ERROR "File or directory ${_file} referenced by variable ${_var} does not exist !")
endif()
endmacro()
macro(check_required_components _NAME)
foreach(comp ${${_NAME}_FIND_COMPONENTS})
if(NOT ${_NAME}_${comp}_FOUND)
if(${_NAME}_FIND_REQUIRED_${comp})
set(${_NAME}_FOUND FALSE)
endif()
endif()
endforeach()
endmacro()
include("${CMAKE_CURRENT_LIST_DIR}/sample-export.cmake")
Error:
There's a difference in the generated config file whether I install those files to Resources/CMake or to Versions/B/Resources/CMake although both point to the same directory.
When installing via the Resources link to Resources/CMake the call to set PACKAGE_PREFIX_DIR is generated as
`get_filename_component(PACKAGE_PREFIX_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../" ABSOLUTE)`
but when installing via Versions/B/Resources/CMake it is generated as
`get_filename_component(PACKAGE_PREFIX_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../../../" ABSOLUTE)`
As a consequence of this the package cannot be found by find_package(sample CONFIG) when installing to Versions/B/Resources/CMake.
Did anybody was facing this error before?
Thanks for any input on this.
