Found missing dependency for program but can't install it

Hello,
I currently try to install Desura on my system.
I extracted everything and tried to execute the desura file which gave me an error for a missing library.

"ldd /home/user/Downloads/desura/desura" informed me that:
"libXpm.so.4 => not found"

Then I used "apt-file search libXpm" which resulted in this:

libxpm-dev: /usr/lib/x86_64-linux-gnu/libXpm.a
libxpm-dev: /usr/lib/x86_64-linux-gnu/libXpm.so
libxpm4: /usr/lib/x86_64-linux-gnu/libXpm.so.4
libxpm4: /usr/lib/x86_64-linux-gnu/libXpm.so.4.11.0
libxpm4-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libXpm.so.4.11.0

I installed (sudo apt-get install libxpm4) the listed library (as this seemed to be the one) and again tried to execute the
file and check the libraries with ldd but still had the same issues although I installed libxpm4.

What can I do to get this going?

Greetings,
Joshua
