I just built OCE on msys2, W7, 32 bits (but not yet tested the examples)
OCE is easy to install with Git.

Due to a lot of files to include or link, I had to use the response files (.rsp files) in makefiles
(the command lines were too long without response files).
I slightly patched cmakelists.txt (attached the patch which enables the response files).
