    flags for position independent code generation.
    
    In almost all cases, this means duplication of the
    CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
    assumed pie equivalent for the _PIE case.  Note that the GNU compiler
    has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
    Windows or Cygwin.
    
    There is a possibility that the _PIE variables are not correct.
    However, as there is no backwards compatibility to be concerned about
    (as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
    the current state suffices.
