CMake: How to use an imported .so.1.2.3 in transitive dependencies - linux

Question

I have to import a libft4222.so.1.2.3 into a CMake project on Linux. There are no symlinks without version information like a plain libmyimportedlibrary.so. I am writing a FindLibFT4222.cmake to make the library usable in my project.
In my project, a shared library uses libft4222 like this:
if (LIBFT4222_FOUND)
if (NOT TARGET LibFT4222::LibFT4222)
add_library(LibFT4222::LibFT4222 UNKNOWN IMPORTED)
set_target_properties(LibFT4222::LibFT4222
PROPERTIES IMPORTED_LOCATION ${LibFT4222_LIBS})
target_include_directories(LibFT4222::LibFT4222
INTERFACE
${LibFT4222_INCLUDE_DIR})
endif()
endif()
LibFT4222_LIBS points to the imported location of the libft4222.so.1.2.3:
/path/to/libft4222.so.1.2.3
I am adding this library as a dependency to a shared library A in my project.
Finally, I have an executable depending on A.
When I link the executable, the linker reports an error that it cannot find libft4222.so
When I add libft4222 directly to the executable, it works.
The error message I get:
/usr/lib/gcc-cross/arm-linux-gnueabihf/9/../../../../arm-linux-gnueabihf/bin/ld: warning: libft4222.so, needed by libSomeOtherLib.so, not found (try using -rpath or -rpath-link)
How do I tell CMake to correctly handle libft4222.so.1.2.3 and not to omit .1.2.3?
Update 1: I looked at the SONAME property of libft4222.so.1.2.3:
$ arm-linux-gnueabihf-objdump -p libft4222.so.1.4.4.44 | grep SONAME
SONAME libft4222.so
So I guess creating the symlinks is unavoidable.
