[CMake] Interface Libraries allow include directories but not link directories.. Why?

[Brian Davis]

Upon further reflection the abs paths for every lib is absolutely not
defensible.

1) Pass only the short lib name to target_link_libraries
2) Add absolute path to future target_link_directories if you must

Then it's one (1) long path on the command line string and not N long paths
fore each lib

I seriously can't believe in 2017 I am actually having this conversation.

Did I miss something here or does Kitware really mean to have package
maintainers spec

target_link_libraries(
    targ
    INTERFACE
    C:\projects\lib1\install\lib\lib1
​    C:\projects\lib1\install\lib\lib2
​    C:\projects\lib1\install\lib\lib3
)

and not

​target_link_libraries(
    targ
    INTERFACE
    lib1
    lib2
    lib3
)

target_link_directories( targ INTERFACE C:\projects\lib1\install\lib )

Does Kitware understand the length problem on command line tools and get
the difference I am trying to convey here?  As far as cmd line would go
"one of these is not like the other", but would have same effect.   If
implemented for projs like ITK maybe I could build is a place other than C:\
