Hi Nick,
Any updates on this patch?
Cheers

I've transfered this thread to the developer list. See below for

Both of the above are expected default behaviors. Both can be
changed by CMake properties like RUNTIME_OUTPUT_DIRECTORY and
its per-configuration equivalent. All CMake generators must
honor these.
None of these locations are the native location
where Xcode would put a build result.
Xcode has settings like CONFIGURATION_BUILD_DIR to control
where the build outputs go. This already works. Is there
some reason your changes cannot use these?
My understanding is that the main problem with the current generator
is all the extra build phases and OTHER_LDFLAGS stuff used to deal
with link line ordering and static libraries. This is what Bill
summarized:

I'm more interested in a solution to implementation issues like these
than in interface details like where output files go.

So, for Xcode and VS IDE, CMake will place things in directories like
Debug, Release.
For example, you should get something like this:
${RUNTIME_OUTPUT_DIRECTORY}/Debug/myexe
Xcode does support building multiple configurations like Debug, Release,
etc. Where is the native location for those files?
As I said, it is per-user xcode settings. You cannot infer the location
from source tree cmake has access to.
At build time, the location is known within xcode. So, I added a copy-file
phase to have xocde copy the resulting binary from the native location to
the standard location the cmake expects. There is little overhead for this.
I've now have a patch which:
1) preserves link order
2) builds libraries into the xcode native location
4) removes pre and post shell script phases previously used to fix
dependency problems
3) xcode projects now have proper dependencies
WIth this cmake patch, I can build CMake.xcodeproject, open it in xcode,
build-all, set the current target to be cmake, make a source change, hit
build, and have xcode just compile that one file, re-archive the library,
then re-link cmake tool. I also debugged all this in Xcode by setting
arguments for the cmake tool and hitting the build-and-debug within xcode!
Attached is the patch from cmake-2.8.3 sources:
This cmake also creates an xcode project that builds LLVM. It is still not
quite optimal because there are a bunch of cases where custom rules cause a
custom make file to be generated which is executed from within xcode via a
shell script phase. Xcode does not now which files the script might modify,
so xcode has to be conservative and re-check all timestamps. There are ways
to add custom scripts with specified input and output files in xcode. I may
get to fixing that someday...
How does one run the test suite? I saw the instructions about building
cmake for make, then executing make Experimental. I did that and all 184
or 184 tests passed. But it looks like this is running the cmake generated
makefiles - not cmake generated xcode projects.
