You should install some tools and thirdparty libraries. For Ubuntu users, you can use the following command(similar for other Linux users):

sudo apt-get install build-essential pkg-config cmake qtbase5-dev qt5-default libfreetype6-dev

git clone https://github.com/xiangxw/mupdf-qt.git
cd mupdf-qt
git submodule update --init --recursive

cd mupdf
make

cd ..
mkdir build
cd build
cmake ..
make

git clone https://github.com/xiangxw/mupdf-qt.git
cd mupdf-qt
git submodule update --init --recursive

Go to platforms/win32, open mupdf.sln and build.

Install Qt5 and add path of qmake.exe to PATH

Launch CMake(gui version), set source code directory and build directory. Configure and generate mupdf-qt.sln. Open mupdf-qt.sln and build it.

git clone https://github.com/xiangxw/mupdf-qt.git
cd mupdf-qt
git submodule update --init --recursive

Install MSYS and MinGW (http://www.mingw.org/wiki/Getting_Started). Using the Graphical User Interface Installer, mingw-get-setup.exe, is recommended. During installation, "checking/ticking" the following in "Basic Setup" is recommended:

1. mingw32-base
2. mingw32-gcc-g++
3. msys-base
4. mingw-developer-toolkit

Add C:\MinGW\bin; to your PATH system variables (at the beginning).

cd mupdf-qt
make build=debug NOX11=yes

For release, just change "debug" to "release". NOX11 is necessary since X11 headers are not available in Windows. Note that this will not build the "app" packaged with the MuPDF source.

Install CMake.

Open CMakeLists.txt with Qt Creator(Qt5 built with mingw), run cmake and build mupdf-qt
