 There is a very extensive code in simd/CMakeLists.txt that handles a
 lot of platforms.
 
 I'm not quite sure why amiga/m68k is mishandled; my best guess is
 because the code wants to support AmigaOS 4 (which provides SIMD
 support).
 
 I don't have an Amiga to debug this. If you find it too much effort,
 you can add something like
 
 .if ${MACHINE_ARCH} == m68k
 CMAKE_CONFIGURE_ARGS+=  -DWITH_SIMD=FALSE
 .endif
 
 to disable SIMD detection/support.
