I hate to hash this back out again, but I wanted to provide a safety warning to cross-compilers on debian hosts.
The changes to CMakeFiles.txt with the package config is spot on.. the issue is with debian.. there’s a problem with pkg-config and cross compilation.
if you execute the correctly generated pkg-config application, it fails for debian with the error message:
“Please install dpkg-dev to use pkg-config when cross-building”
And because of this, pkg config won’t find the correct mingw SDL2 additional cflags.
This is super stupid since dpkg-dev is already installed. A little more research pointed to a bug raised in 2020 that has been addressed but not released (mingw-w64 bug #930492). this patch is released in mingw-w64 version 7.0.0-3. The current installed version is 6.0.0-3.
If you’re hell bent on making it work, you will need to comment some lines in /usr/share/pkg-config-crosswrapper/
