Visual Studio Express editions do not support solution folders,
so default behavior should be as if USE_FOLDERS global property
is OFF.
Also, allow folder names to be the same as target names: internally,
use a prefix to distinguish folder GUIDs from target GUIDs. Add
a target and folder with the same name in the ExternalProject
test to exercise this code.
For CMake itself, provide a new option CMAKE_USE_FOLDERS that
defaults to ON so that Visual Studio users get a nicely organized
CMake project. Express edition users will have to turn off the
CMAKE_USE_FOLDERS option in order to build CMake in the VS Express
IDE.
VS10 uses MSBuild underneath. The <Message></Message> CDATA are just
appended to "echo" and executed as a single command. Encode the message
such that it can be passed to echo. Convert newlines to tabs since they
cannot be printed this way.
In targets with no non-header files the linker language cannot be
determined. Since the target project file cannot be generated at all in
this case, give up as soon as it is detected. Otherwise the generation
code may try to run with uninitialized information.
Reverting abandoned topic xcode_source_group_fix_7932 left this source
slightly different due to trailing whitespace removal on some lines.
Remove all trailing whitespace from the file to make it consistent.
The original implementation of this generator accidentally used
"$(Configuration)/" for source-specific object file names. Correct it
to use "$(IntDir)/" just like the generators for all previous VS
versions. The target-wide output directory is "$(IntDir)/" already.

OK, on windows 7 after we untar some files,
sometimes we can not rename the directory after
the untar is done. This breaks the external project
untar and rename code. So, by default we will wait
1/10th of a second after the untar. If CMAKE_UNTAR_DELAY
is set in the env, its value will be used instead of 100.
With CMAKE_OSX_ARCHITECTURE settings such as $(ARCHS_STANDARD_32BIT),
the space inserted by the for loop would confuse Xcode if quoted. In
this particular example, what would be output would be:
ARCHS = "$(ARCHS_STANDARD_32BIT) ";
The Xcode UI does not recognize this as the built-in "Standards 32-bit"
architecture setting unless the space is removed.
