如何在cmake中指定linux二进制文件的rpath

Question

I have a CMakeLists.txt file that contains such line of code:

link_directories(dir_a dir_b dir_c)

When I build an executable and perform

readelf -d

on it, I see RPATH with dir_a, dir_b dir_c.

What can I do with cmake if I want to create

• Executable with empty RPATH?
• Executable with some paths, but not specified in link_directories line?

The executable is not supposed to be "installed".

From this cmake-documentation you can read that:

• you can use the variable CMAKE_SKIP_RPATH to have cmake not adding any RPATH to a binary ever and
• that with the SET_TARGET_PROPERTIES -functions RPATHs can be controlled individually on a per-target base.
