[devel] Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for

installing libpng in /usr/lib64 (Funda Wang).  Also ported other recent
changes from libpng-1.4.4beta07:
  Revised CMakeLists.txt to put the man pages in share/man/man* not man/man*
  Revised CMakeLists.txt to make symlinks instead of copies when installing.
  Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman)
