Hi, I am trying to build Openslide for Windows 10 64bit using Cygwin.</p>

I have followed the instructions in ReadMe file and I am keep running into the same error while building libpng.</p>

For Cygwin system, I currently have<br style="box-sizing: border-box">

<p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 16px">From what I am searching online and seeing in the command prompt, it seems like its most likely due to a version issue with the package version of programs such as make, cmake, mingw64
gcc, etc. Can someone provide me with a working versions of each necessary programs?</p>
