# This macro alters the behavior of find_package and find_library.
# It does this by setting the CMAKE_FIND_LIBRARY_SUFFIXES global variable.
# You should save that variable before calling this function and restore it
# after you have accomplished your goal.
#
# The behavior is altered in two ways:
# 1. We always find shared libraries, never static;
# 2. We find shared libraries with the given version number.
#
# On Windows this function is a no-op. Windows does not encode
# version number information information into library path names.
