In Verifier.sol
Function verify(unit[] input, ...)
The public input seems to be restricted to unit, if I want to check that a given hash is the hash of a preimage (in that case the public input would be a bytes32), would that also work? If not could we make some minor changes so that would work?

Following the tutorial directly, I had to do this step before the step to build with cmake.

If you try to build and see that libsnark is missing a CMakeLists.txt file then you should run git submodule init && git submodule update after git clone.

This is on macOS but shouldn't matter.

The error I am getting while running cmake

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

Hi, thanks for this repo. I want to learn that how to implement zk-snark, algorithms etc. Is it possible that fix the broken link? The link is: https://media.consensys.net/introduction-to-zksnarks-with-examples-3283b554fc3b

Thanks.

In the tutorial it should be make .., instead of make?
