I could successfully build OpenCV320 for android under Windows10 using cmake, targeting armeabi-v7a and arm64-v8a abis

Now I am trying to build it with "armeabi-v7a with NEON" to check performance differences. Build process works ok, but when I try to run, it crashes at the first JNI call (SISEGV error...).

So my question is if this is a known issue, or on the contrary perhaps there is some other cmake option that "must go together" with -DANDROID_ABI="armeabi-v7a with NEON" so that it can work correctly, or just I did something wrong.

Any input will be welcome :)

--edit-- Also a good starting point would be to find wich cmake options can be used to build the officially released 3.20 from master.
