"""pyWindeployqt

This is a wrapper for  mingw32 objdump replacing windeployqt which is missing from MXE
I don't know why they disabled it, but here it is.

Example:
./deploy.py --build=~/ClionProjects/project/build/ \
--objdump=/home/user/mxe/usr/bin/i686-w64-mingw32.shared-objdump \
~/ClionProjects/project/build/project.exe;
