关于在linux平台或cygwin平台运行opencv出现Illege instruction(core dump)问题的缘由

在linux或cygwin平台运行opencv程序时，会出现Illege instruction (core dump)问题，原因的解释来自：

• If you happen to get “Illegal instruction” while running applications using OpenCV, you should disable some CPU performance tunning in OpenCV makefiles (Actually cmake files). Edit OpenCV/release/CMakeCache.txt, settingENABLE_SSE2:BOOL=OFF. Then rerun cmake, make, make install. This is very common with old AMD CPUs (like Athlon XP).
