[CMake] Distinguishing processor type for -march -mtune arguments

Mon, 14 May 2007 14:10:55 -0700

Is there a way to distinguish processor type more than what CMAKE_SYSTEM_PROCESSOR tells me?
Currently I can't tell the difference between a pentium M and pentium 4 (both read i686) and various 64 bit architectures such as opteron versus pentium (both read x86_64). 


I'm looking for a way to automate the -mtune argument to gcc on various 
systems.


Thanks,
James
