No.  CMAKE_RUNTIME_OUTPUT_DIRECTORY only affects the locations of
the .dll files, not .a/.so/.lib.  Also CMake already knows where
the library files will be and links via absolute path.  Link
directories are almost never needed.

No.  In general one should not depend on PATH for .dll locations
within your own project.
