I'm not interested in maintaining this, but I did have to build
it because the last release is from 2016 and the released binary
doesn't run on debian bullseye. In case someone does want to
package it, maybe this will help them. I initially tried building
against the system ffmpeg, but the build failed so I ended up just
disabling ffmpeg support.
Here's what I did to build stepmania 5.1.0-beta2, after unpacking the source:
apt-get install cmake libgtk2.0-dev libjpeg-dev libmad0-dev libvorbis-dev nasm libudev-dev libbz2-dev libva-dev libglew-dev libpulse-dev libjack-dev libasound2-dev
# note: this following step probably isn't necessary when ffmpeg
is disabled. To enable it, you'd do cmake -D WITH_SYSTEM_FFMPEG=ON
apt-get install libavcodec-dev libavformat-dev libswscale-dev
cd Build
cmake -D WITH_FFMPEG=OFF ..
make
make install
