To at least see if 3.13 will support your use case, you could
try a nightly binary from here:

  https://cmake.org/files/dev/?C=M;O=D

Use `$<TARGET_FILE_DIR:mytarget>/..` to refer to a path relative
to the target file location.

I've never seen a need to adjust link flags based on the target
location.  CMake has several features for RPATH support.  What
are you really trying to do?
