How to get CMake find_file to accept UNIX-style paths on MSYS2?

I'm using CMake 3.4.1, on Windows 10, with MSYS2 (everything up-to-date as of Dec. 25 2015).

When I use CMake's find_file command, it won't work unless the path is in Windows-style. This is a problem for me, because I'm trying to use findwxWidgets.cmake, which fails because of this.

For example:

CMakeLists.txt:

cmake_minimum_required(VERSION 3.0)
find_file(version_h version.h PATHS /mingw64/include/wx-3.0/wx)
message(STATUS "version_h: ${version_h}")

Running cmake spits out:

-- version_h: version_h-NOTFOUND

But it's clearly in there:

>>> file /mingw64/include/wx-3.0/wx/version.h
/mingw64/include/wx-3.0/wx/version.h: C source, ASCII text

I'm wondering if this is a bug, or if there's some obscure flag I have to set to get this to work. How do I get CMake's find_file to find files with UNIX-style paths?
