No, cmake doesn't offer such generic flags.
The only thing it has is such a generic setting for IPO optimization, but I 
think that's about it.

It would indeed be nice to have such a thing.  VTK currently has a
similar problem where it passes -std=c99, a gcc flag unrecognised by clang:

[CMake] Enabling C++0x support

2011-05-04 Thread Guido Winkelmann 
Hi,

Is there a way to specify, in a cross-platform compatible manner, that a given 
C++ source file (or a target or an entire project) requires support for C++ 0x, 
so that whatever compiler flags would be necessary for that for the current 
platform and compiler will be set?

For example, when using GCC, you need to pass "-std=c++0x" as an argument to 
the compiler in order to get C++0x support. I could just set(CMAKE_CXX_FLAGS 
"-std=c++0x"), but that's not really portable... the current platform might 
use a different compiler that needs a different option to enable C++ 0x and 
won't understand "-std=c++0x", or, at some point in the future, it might use a 
GCC release which makes 0x the default and does not even need a special flag.
