Difference Between Static and Dynamic Libtorch

I used the following links to download static and dynamics versions of the libtorch, but both seem the be the same build:

I was expecting to see libc10.a, libtorch.a, etc. Apparently, there is something wrong in build process of static binaries. I also compared the binaries using “diff” command and both are exactly the same.

It looks like that the build process does not set BUILD_SHARED_LIBS=OFF
Can someone provide more details?
