Compiling in Ubuntu 20.04 with an SDL2 error

[jason-mehmel]

I'm trying to compile IVAN from the releases, following the directions in the INSTALL guide.

When I get to cmake ~/Downloads/Attnam-ivan-87f4a33/

I get what is below! I've got all the SDL2 libraries that I can see in my repositories, so I'm not sure what I'm missing!

Have you installed SDL2_mixer on your build machine?

apt-get install libsdl2-mixer-2.0-0

I thought I had them, but I didn't have the libsdl2-mixer-dev installed.

I installed that one, and it compiled! Thank you for the help!
