I'm attempting to use GTK+3 to create a Desktop, but I am having a problem installing all of the dependencies.  I keep getting the following error:  GUI cabal: version >=0.9.0 of pkg-config is required

I understand this error message as: You need to install pkg-config first. pkg-config is the tool that manages path and versions of installed C libraries and Cabal uses it to query existence and compiler flags of installed C libraries.

I am using Cygwin on a Windows 10 operating system. What is needed to fix this? Is this the best way to do a desktop GUI in Haskell?

On Windows I used MSYS2 and this helped a lot to install components like pkg-config and other C libraries plus their interfaces.
