Summary0008915: Missing feature to set Xcode specific build settings
DescriptionXcode has two ways to change build settings: one way is to use compiler flags (e.g. -fno-exceptions to disable C++ exceptions); another way is to use Xcode specific variables (e.g. GCC_ENABLE_CPP_EXCEPTIONS). Some settings, such as is the case for exceptions, have both a compiler switch and a build setting variable. Other settings can only be changed with variables (e.g. the compiler version (3.3/4.0/4.2) to build the project).

A previous mail by Bill Hoffman on the cmake mailing list mentioned CMAKE_OSX_ARCHITECTURES, which results in the build setting variable ARCHS being written into the Xcode project file. However, there doesn't seem to be a generic way to set a build setting variable.

I'd like to ask for a new feature that allows me to set any Xcode build setting variable. These settings are important because they control many aspects of the Xcode build process that can't be configured with compiler switches.
Steps To Reproduce
Additional Informationcmake 2.6-patch 3, Xcode 3.1.2, Mac OS X 10.5.6

You can modify Xcode settings using the XCODE_ATTRIBUTE_<an-attribute> property, e.g. set_target_properties(target PROPERTIES XCODE_ATTRIBUTE_GCC_ENABLE_CPP_EXCEPTIONS "NO"). You might have to set the corresponding compiler flag (if there is one), too, but I'm not sure about that. Is that the kind of feature you are requesting?

Yes, this is what I'm looking for. Thanks for your help.

(I don't know how to close the issue. I think you will have to do that.)

In addition to the target property, see the top level variables beginning with CMAKE_XCODE_ATTRIBUTE_* as introduced by the fix for 0009125
