Ah, the bug didn't say that it had been released yet, just that it was in cvs. Sorry for the trouble. Thanks!

It is Xcode-generator specific, though, and has no effect on generated files for other build systems.

This works fine for the makefile generator, but it breaks with the XCode generator for Xcode 3.2 as the default gcc is v4.2. Other posts on this list indicates that it's a bug in the Xcode generator. I would like to workaround this issue somehow until a new version of cmake is released. One poster suggested using gcc's -V option, which allows forcing the gcc version. I've tried injecting this into the CMAKE_CXX_FLAGS like this: if (${CMAKE_GENERATOR} MATCHES "Xcode") set(CMAKE_CXX_FLAGS "-V 4.0 ${CMAKE_CXX_FLAGS}") endif(${CMAKE_GENERATOR} MATCHES "Xcode") However, this creates a new error: '-V' must come at the start of the command line It seems that the CMAKE_CXX_FLAGS are always appended to the constructed gcc command. Is there some way that I can prepend flags (that is, put them at the very beginning of the command-line)?
