#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
Do not attach a custom command to a target if it is already attached to one of
the target's dependencies. The command's output will be available by the time
the target needs it because the dependency containing the command will have
already been built.
Since commit fb45559e09 (Xcode: Process targets in depth-first order during
generation, 2018-07-19, v3.13.0-rc1~293^2) we generate a target only after
generating its dependencies. Therefore when visiting the custom commands in a
target, we can assume that custom commands in its dependencies have already
been visited.
The Xcode 'new build system' rejects empty signing identities unless
signing is explicitly marked as not allowed. Update test cases where we
turn off signing to explicitly disallow it too.
Also turn off signing in the XCTest test.
Since commit 7249ba9677 (ExternalProject: Enforce that patch depends on update,
2020-04-03, v3.18.0-rc1~403^2) we do not need the workaround in the
MultiCommand case.

Only generate a graph dependency between a custom command and
a target when the custom command queries for the file path
of an artifact of the target.
This makes generator expressions such as `TARGET_FILE_DIR`
behave the same way as `TARGET_PROPERTY` which never generated
a graph dependency.

For Qt >= 5.15.0 and Ninja generators AutoMoc creates a depfile to let
Ninja decide when to run AutoMoc. This was introduced by commit aebfbcaa46
(AutoGen: Use depfiles for the XXX_autogen ninja targets, 2020-01-14,
v3.17.0-rc1~58^2).
However, AutoMoc was not triggered after adding a new moc-able file to
the project. This patch adds the project file (and potentially included
files) to the dependencies in the depfile.
Now, a re-run of AutoMoc is triggered if the project file changes.
Fixes: #21127
