Ncnn: android 编译没有生成.so文件

[ghost]

按照cmake 打包 android sdk一问的说明，结果如下，并且在cmake的时候出现的大量的warning，最后只生成了.a 文件，没有.so文件，请教各位

主项目生成的是 libncnn.a
so 文件是用 examples 的 squeezencnn/jni 里的代码生成的，手工修改 Android.mk 里的 libncnn.a 路径，ndk-build

@nihui 请教大牛
使用gcc4.9.4时, 检测openmp成功了,为什么Could NOT find OpenMP?",
-- Performing Test OpenMP_FLAG_DETECTED
-- Performing Test OpenMP_FLAG_DETECTED - Success
-- Could NOT find OpenMP (missing: OpenMP_C_FLAGS OpenMP_CXX_FLAGS)
