[vtkusers] X11 CMake Errors on Mac

[David Gobbi]

I can expand on this a bit, and give my own perspective. A bundled app on
OS X can find run-time libraries in three ways:

1) it can find them in the system paths, e.g. in /usr/lib or in
/System/Library/Frameworks

2) it can find them within the bundle itself, i.e. within
MyApplication.app/Contents/MacOS or in
MyApplication.app/Contents/Frameworks/

3) it can find them in the DYLD_LIBRARY_PATH

When I'm ready to deploy my app I do a "make install" that copies all the
Qt and VTK libraries into my bundle.  CMake can automatically figure out
the dependencies and modify the libraries and the executable so that they
can find each other within the bundle, which makes it unnecessary to use
DYLD_LIBRARY_PATH with a bundle created via "make install".

But like Mike suggested, I stick to using DYLD_LIBRARY_PATH and running my
programs from the terminal until I'm ready to deploy them.  It's only when
I'm ready to deploy that I do a "make install" to create a stand-alone
bundle.
