Electron libportaudio image not found - binding.gyp enhancement

[DevChanQ]

I got hit with the Image not found error for libportaudio when I packaged up my electron application and ran it on a different machine, application ran fine on the development machine though. After digging through some documents about node-gyp, I was suggested to look for the linker section of the naudiodon.node binary and found out that the LC_PATH was set to an absolute path of the build/Release path on my development machine. What I did to make it work was to change the OTHER_LDFLAGS of OS=="mac" to "-Wl,-rpath,@loader_path/" which tells the linker to look for libraries relative to the binary file location.

Hi, thanks for the feedback, I'm sorry you hit a problem.
I don't have access to a Mac at the moment but if you would like to test this change and raise a PR I'm happy to update.

I can confirm this indeed fixes the Image not found problem

Can confirm the above works as well. I.E changing to snippet below in binding.gyp:

  "conditions" : [
    [
      'OS=="mac"', {
        'xcode_settings': {
          'GCC_ENABLE_CPP_RTTI': 'YES',
          'MACOSX_DEPLOYMENT_TARGET': '10.7',
          'OTHER_CPLUSPLUSFLAGS': [
            '-std=c++11',
            '-stdlib=libc++',
            '-fexceptions'
          ],
          'OTHER_LDFLAGS': [
            "-Wl,-rpath,@loader_path"
          ]
        },

Please update this if possible. Looks like someone has already put in a PR for this:
#51

Just needs to be approved.

Many thanks
