Build on Windows

The native Windows build is complicated and error-prone. As of 2016-06 the preferred way by @koppi to build bpp for Windows is to cross-compile bpp using mxe:

cd /opt
git clone https://github.com/mxe/mxe.git
cd mxe
export PATH=`pwd`/usr/bin/:$PATH
nice make MXE_TARGETS='i686-w64-mingw32.shared' qt5  QT5_BUILD_TYPE=-debug-and-release lua luabind bullet assimp freeglut

Download and build libQGLViewer:

git clone https://github.com/GillesDebunne/libQGLViewer
cd libQGLViewer
/opt/mxe/usr/i686-w64-mingw32.shared/qt5/bin/qmake
make

Download and build bullet

apt-get source bullet # bullet_3.06+dfsg.orig.tar.xz

cmake . -DCMAKE_TOOLCHAIN_FILE=/opt/mxe/usr/i686-w64-mingw32.shared/share/cmake/mxe-conf.cmake -DBUILD_DEMOS:BOOL=OFF -DBUILD_EXTRAS:BOOL=OFF -DBUILD_UNIT_TESTS:BOOL=OFF -DBUILD_SHARED_LIBS:BOOL=ON -Wno-dev . -G "Unix Makefiles"
make
make install
