Building upplay with MinGW

First install MinGW and Qt 5.5.

Also install innosetup, this will be used to create the installer.

Start a command window running the Bash shell, using C:\MinGW\msys\1.0\msys.bat

Change the PATH to use the tools wich come with Qt 5.5, not the ones from the MinGW install (which is mostly there to provide bash and tar actually…).

export PATH=c:/qt/tools/mingw492_32/bin:$PATH

libupnp

Clone it from https://github.com/medoc92/pupnp16, use the default branch pupnp16-fixes, and follow the instructions in README_MINGW.txt

curl 7.43.0

Download curl Extract it:

cd c:\temp
tar xf curl-7.45.0.tar.gz

Have a look at curl-7.45.0/docs/INSTALL: MinGW32 section

Do not run configure, just "make mingw32"
```
cd curl-7.45.0
make mingw32
```

expat

Download expat 2.1.0

Extract

cd expat-2.1.0
configure
make

libupnpp

Copy windows/config_windows.h to libupnpp/config.h

Then use windows/qmk/libupnpp.pro, possibly adjusting paths

upplay

Open upplay.pro with Qt Creator. Possibly adjust the paths to libupnp/curl/expat and libupnpp, build.

Then use the windows/mkinstdir.sh to create an installation directory, and use the innosetup file windows/innosetup/upplay-setup.iss to create the installer.
