c++ - How to specify linux binary's rpath in cmake -

i have cmakelists.txt file contains such line of code:

link_directories(dir_a dir_b dir_c) 

when build executable , perform

readelf -d 

on it, see rpath dir_a, dir_b dir_c.

what can cmake if want create

• executable empty rpath?
• executable paths, not specified in link_directories line?

the executable not supposed "installed".

from cmake-documentation can read that:

• you can use variable cmake_skip_rpath have cmake not adding rpath binary ever and
• that set_target_properties-functions rpaths can controlled individually on per-target base.
