How to cross-build libfreenect for Windows on e.g. Ubuntu Linux

== Compile libusb (v1.0.26 or git) ==

Below instructions assume this is built in ~/SRC/libusb

 cd ~/SRC/libusb
 ./configure --host=x86_64-w64-mingw32
 make -j5

== Compile freeglut (v3.2.3 or git) ==

Below instructions assume this is built in ~/SRC/freeglut
Follow the instructions in the README.mingw_cross but with
the addition of this cmake flag:
 -D FREEGLUT_REPLACE_GLUT=1
(Note the dll will actually end up in the bin folder)

== Compile libfreenect ==

This can surely be improved, the system FindGLUT doesn't work well.
Also the included FindThreads.cmake doesn't seem to help in this case.

 touch ../cmake_modules/FindGLUT.cmake

 cmake -D CMAKE_TOOLCHAIN_FILE=mingw.cmake \
       -D LIBUSB_1_INCLUDE_DIR=~/SRC/libusb/libusb \
       -D LIBUSB_1_LIBRARY=~/SRC/libusb/libusb/.libs/libusb-1.0.dll \
       -D THREADS_PTHREADS_WIN32_LIBRARY=/usr/x86_64-w64-mingw32/lib/libpthread.dll.a \
       -D GLUT_FOUND=1 \
       -D GLUT_INCLUDE_DIR=~/SRC/freeglut/freeglut/include \
       -D GLUT_LIBRARY=~/SRC/freeglut/freeglut/bin/libglut.dll \
       -D CMAKE_INSTALL_PREFIX=install-win \
       ..

 make -j5
 make install
 find install-win

This results in dynamically linked executables, so you'd need
libusb.dll libglut.dll libphreads-1.0.dll on the target computer.
