Thanks Jakub. Mixing your proposal and [mistral codestral’s one](https://mistral.ai/fr/news/codestral) I’m getting:

```cmake
get_property(ImportedTargets DIRECTORY "${CMAKE_SOURCE_DIR}" PROPERTY IMPORTED_TARGETS)
list(FILTER ImportedTargets INCLUDE REGEX "^${PackName}::")

if(ImportedTargets)

	# Creating the main component
	add_library(${PackName}::${PackName} INTERFACE IMPORTED)
	# Adding the found components as dependencies
	if(ImportedTargets)
		target_link_libraries(${PackName}::${PackName} INTERFACE ${ImportedTargets})
	endif()

endif()

```
