[CMake] How to get RPATH option (-Wl, -rpath, /path/to/local/lib) ?

[Kris Thielemans]

Hi

There a wiki page covering this

https://cmake.org/Wiki/CMake_RPATH_handling

 

I find it a bit confusing (and the example code for the “full RPATH” option
seems to set CMAKE_INSTALL_RPATH twice), but it should help. 

 

It might be outdated for OSX as El Capitan introduced extra security
requirements such that the recommendations on the wiki no longer seem to
work. You can see some of our struggles with this here

https://github.com/CCPPETMR/SIRF/pull/79

We seem to have found a solution using CMAKE_INSTALL_NAME_DIR but any other
help with that appreciated.

OK, so I believe I just need to write "-Wl,rpath" in my templates of
pc/cmake files !...

How to get RPATH option (-Wl,-rpath,/path/to/local/lib) ?

 

I would like to create a *.pc/cmake file for users to find a library I
provide. As there is possibly a LOT of dependencies (libraries) I may not
even be able to list, the most simple way to do that is to use RPATH. I know
that for gcc, RPATH is set with "-Wl,-rpath". But what about others
compilers (pgi, icc) ? This option could not be the same.

 

Is it possible to "grab" the correct RPATH option (-Wl,-rpath) according to
the compiler ? Something like a CMAKE_RPATH_OPTIONS to substitute in a
*.pc/cmake.in template file ? (to create a *.pc/cmake file in the install
directory using configure_file)
