How to set rpath origin in cmake?


I found Cmake: How to set rpath to ${ORIGIN} with cmake but my cmake does not have target_link_options.

I'm not installing the binary, I'm only "installing" it with RUNTIME_OUTPUT_DIRECTORY, so I don't think CMAKE_INSTALL_RPATH will work. Even though, I tried SET(CMAKE_INSTALL_RPATH "$\{ORIGIN\}") as suggested in the question, but I got

  Syntax error in cmake code at

  .../CMakeLists.txt:25

  when parsing string

    $\{ORIGIN\}

  Invalid escape sequence \{

I need to set this rpath which I was using in Makefile:

-rpath=\$$ORIGIN/lib

How to do it in cmake?


Solution

  • Following works for me on 3.14

      set(CMAKE_INSTALL_RPATH $ORIGIN)
    

    This is what Craig Scott recommended in his CppCon 2019 talk Deep CMake for Library Authors (Slide 100/110)
