[CMake] LOCATION target property, generator expressions

[Hendrik Greving]

Is there any way before 3.13 to achieve what I need? Right now we modify
LINK_FLAGS based on something that is computed with values from LOCATION.
For CMP0026, I'd like to get rid of LOCATION. As pointed out earlier,
unclear how this would work e.g. by using file(GENERATE.. in this case.
Thanks in advance
