ImageMagick 7 port to Android.

Last changes

  • Image Magick updated to latest version
  • clang toolchain supported. required Android NDK r15 to build (early versions had issues with OpenMP support)
  • all binaries moved to github release section

  • 3rd party libs actual at 2017.03
  • OpenMP build by default (with gcc 4.9 and clang 5.0.3)
  • MagickWand
  • Magick++ disable due to crash
  • latest binaries: v0.4.70710
