DLLs have been uploaded. I will create a release but until then, select the Code button and Download Zip.  This should give you the entire master branch with the binary and its DLLs.

Otherwise the source code with a scrypt-NAH patch is there at https://github.com/catcoin-project/cpuminer-opt-scryptnah.git, I've found it compiles without many issues on Linux and Windows.  It needs libcurl-dev, libssl-dev (crypto and ssl), pthreads (or winpthreads) on top of the usual build tools (build-essential, autotools-dev, m4, libtool, automake, autoconf, git, .. that should do it).

Let me know how it goes!
