Re: [CMake] How to get RPATH option (-Wl, -rpath, /path/to/local/lib) ?
The wiki do not cover how to handle rpath when you need to provide a mylib.pc
or mylib.cmake file in the install directory of your library: this is why I
asked !
If you need to provide a pc file like this:
>> more mylib.pc
prefix=${CMAKE_INSTALL_PREFIX}
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib
Cflags: -I${includedir}
Libs: -L${libdir} -lmylib
The question is : how do you do when you need RPATH in the pc file ?
Do you hard-code (this may not be portable) the rpath option :
>> more mylib.pc
prefix=${CMAKE_INSTALL_PREFIX}
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib
Cflags: -I${includedir}
Libs: -Wl,-rpath, -L${libdir} -lmylib
Or is there a specific variable to handle this ? Like for instance something
like this
>> more mylib.pc
prefix=${CMAKE_INSTALL_PREFIX}
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib
Cflags: -I${includedir}
Libs: ${CMAKE_RPATH_LINKER_OPTION}, -L${libdir} -lmylib

Re: [CMake] How to get RPATH option (-Wl, -rpath, /path/to/local/lib) ?
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 It might be outdated for OSX as El Capitan introduced extra security requirements such that the recommendations on the wiki no longer seem to work.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.
