# The generated C++ code uses static initializers which mutate a global data
# structure. This causes problems for an executable when:
#
# 1) it dynamically links to two libs, both of which contain generated C++ for
# the same proto file, and
# 2) the two aforementioned libs both dynamically link to libprotobuf.
#
# One solution is to statically link libprotobuf, that way the global
# variables are not shared; in fact, this is necessary for the python Mesos
# binding to not crash, as the python lib contains two C extensions which
# both refer to the same proto schema.
