Failed to find/load Framework library

bob@ubuntu ~/Downloads/xojo2017r2.1 $ ./Xojo
Failed to find/load Framework library cannot open shared object file: No such file or directory

So, I did:
$ sudo apt-get install libgtk-3-dev
The following NEW packages will be installed:
libatk-bridge2.0-dev libatspi2.0-dev libdbus-1-dev libdrm-dev
libegl1-mesa-dev libepoxy-dev libgmp-dev libgmpxx4ldbl libgtk-3-dev
libmirclient-dev libmircommon-dev libmircookie-dev libmircookie2
libmircore-dev libprotobuf-dev libwayland-bin libwayland-dev libx11-xcb-dev
libxcb-dri2-0-dev libxcb-dri3-dev libxcb-glx0-dev libxcb-present-dev
libxcb-randr0-dev libxcb-shape0-dev libxcb-sync-dev libxcb-xfixes0-dev
libxkbcommon-dev libxshmfence-dev libxtst-dev libxxf86vm-dev nettle-dev
x11proto-dri2-dev x11proto-gl-dev x11proto-record-dev

Still unable to load Xojo with Ubuntu 16.04, same error.
How do I install the dependencies to get this working with my version of Linux?

Please Ignore…

Had to do the following setup steps:
Ubuntu 16/17
This installs the necessary GTK+ 3 and other necessary 32-bit libraries:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libglib2.0-0:i386 libsoup2.4-1:i386 libgtk-3-0:i386 libwebkitgtk-3.0-0:i386
