+Subject: [PATCH] Add a build-time option to change the resources directory.
+
+Normally, SameBoy would use executable-relative paths for any
+resource files, which posed problems for packaging the software
+by distributions, which usually prefer FHS-compliant file locations.
+
+This commit makes it possible to specify an alternative base
+directory with a compile-time environment variable.

+-To compile, simply run `make`. The targets are cocoa (Default for macOS), sdl (Default for everything else), libretro, bootroms and tester. You may also specify CONF=debug (default), CONF=release or CONF=native_release to control optimization and symbols. native_release is faster than release, but is optimized to the host's CPU and therefore is not portable. You may set BOOTROMS_DIR=... to a directory containing precompiled dmg_boot.bin and cgb_boot.bin files, otherwise the build system will compile and use SameBoy's own boot ROMs.

++
++By default, the SDL port will look for resource files with a path relative to executable. If you are packaging SameBoy, you may wish to override this by setting the `DATA_DIR` variable during compilation to the target path of the directory containing all files (apart from the executable, that's not necessary) from the `build/bin/SDL` directory in the source tree. Make sure the variable ends with a `/` character.

+ SameBoy was compiled and tested on macOS, Ubuntu and 32-bit Windows 7.
