I know that cmake has some built-in commands including tar. These would be cross platform: https://cmake.org/cmake/help/v3.2/manual/cmake.1.html
I use the tar command within cmake to download and unzip yaehmop on all platforms. The problem, though, is that it looks like you may have to add cmake as a runtime dependency with this setup, and I know you may not want to do that...
