### Windows cross build
TODO!
Set Winbuild flag in CMakeList.txt.
Dependencies:
* MinGW Compiler
* MinGW-libcurl
* MinGW-libconfig++
Optional dependencies
* NSIS Pack tool (for creating installer)
* doxygen (for generating html doc)
Some addition configuration of lib paths may be needed in CMakeList.txt.
`make package` will pack it into a NSIS installer for Windows.
