Dependency Collector
#
# Emanuele Ruffaldi
# Recursive Dependency lister and collector (2017)
#
#
# Tested on OSX crosscompiling Windows using peldd (https://github.com/gsauthof/pe-util)
#
# Example:
# python listlibs.py --peldd ~/bin/peldd --path ~/Documents/work/xcoco/cocolibs/prefixwin64/bin ~/Documents/work/xcoco/cocolibs/prefixwin64/lib ~/Documents/work/xcoco/cocomr/buildmxe/bin /usr/local/mxe/usr/x86_64-w64-mingw32.shared.posix/bin --target ~/Documents/work/xcoco/cocomr/buildmxe/bin ~/Documents/work/xcoco/cocomr/buildmxe/bin/*.dll
#
# Future: test on OSX and Linux
# Future: hide known Windows sytem DLL
