MuPDF builds with MSBuild on Windows (/MT, OpenSSL from vcpkg); Git for Windows' MinGit stands in for the source build there. CEF loads from where libcef lives and sets its API version first on every platform. File identity on Windows compares volume and index. The checkout and reference/ keep LF on Windows.
