Wireshark-dev: Re: [Wireshark-dev] [Wireshark-commits] master 5b62526: OK, try cmake -E copy.

Can you try building from scratch? This might be due to g2cae320 and
gdeabe64, which enabled then disabled running osx-app.sh on the
application bundle. osx-app.sh runs macdeployqt and install_name_tool,
both of which rewrite library paths.

I was hoping to bring the OS X build in line with the Windows build,
which is 1) portable, and 2) impervious to QTBUG-15234. Unfortunately
osx-app.sh slows down the build and leaves wireshark-gtk unusable.

[1] Qt loads shared libraries from hard-coded paths.
