CMake is not required to build gem5. It is only required to build and link the optional DRAMSysm library. Therefore, if the DRAMSys repo has been cloned but CMake is not present this patch ensures no attempt at building or linking DRAMSysm is made. A warning is thrown inform the user of the missing CMake. Change-Id: I4d22e3a16655fd90f6b109b4e75859628f7d532d
