# Keep OLD policy. Code was updated to support the new one but wasn't tested
#
# cmake version 2.8.9
#   CMP0018
#        Ignore CMAKE_SHARED_LIBRARY_<Lang>_FLAGS variable.
# 
#        CMake 2.8.8 and lower compiled sources in SHARED and MODULE libraries
#        using the value of the undocumented CMAKE_SHARED_LIBRARY_<Lang>_FLAGS
#        platform variable.  The variable contained platform-specific flags
#        needed to compile objects for shared libraries.  Typically it included
#        a flag such as -fPIC for position independent code but also included
#        other flags needed on certain platforms.  CMake 2.8.9 and higher
#        prefer instead to use the POSITION_INDEPENDENT_CODE target property to
#        determine what targets should be position independent, and new
#        undocumented platform variables to select flags while ignoring
#        CMAKE_SHARED_LIBRARY_<Lang>_FLAGS completely.
# 
#        The default for either approach produces identical compilation flags,
#        but if a project modifies CMAKE_SHARED_LIBRARY_<Lang>_FLAGS from its
#        original value this policy determines which approach to use.
# 
#        The OLD behavior for this policy is to ignore the
#        POSITION_INDEPENDENT_CODE property for all targets and use the
#        modified value of CMAKE_SHARED_LIBRARY_<Lang>_FLAGS for SHARED and
#        MODULE libraries.
# 
#        The NEW behavior for this policy is to ignore
#        CMAKE_SHARED_LIBRARY_<Lang>_FLAGS whether it is modified or not and
#        honor the POSITION_INDEPENDENT_CODE target property.
