[CMake] automatic library dependencies causing problems

[Clinton Stimpson]

I've found a solution for my problem.

When I build libD.so, I add "-all" to export symbols from the static 
libraries E-H.
Then libA.so and libB.so won't get their own copies of libs E-H, and the 
linker will emit a warning saying that they were ignored.

  IF(CMAKE_SYSTEM MATCHES "IRIX")
    SET_TARGET_PROPERTIES(D PROPERTIES LINK_FLAGS -all)
  ENDIF(CMAKE_SYSTEM MATCHES "IRIX")

Thanks,
Clint
