If multiple ExternalData_Target_Add calls generate the same output file
then we need to avoid calling add_custom_command multiple times with
that output. This was already done within a single target by setting a
variable in the local function scope. This will not be visible in other
calls though so we need to use a directory property instead to prevent
adding a custom command multiple times for one output in a directory.
Normally it is not safe to have multiple custom commands that produce
the same output file across multiple independent targets, but since we
use atomic replacement of outputs the resulting races should not be a
problem. For the convenience of projects, tolerate this instead of
diagnosing it. In particular, we previously allowed up to two copies
of the custom command in one directory because CMake has a fallback
from MAIN_DEPENDENCY to an `<output>.rule` file.
While at it, add a note to the documentation that typically only one
external data target should be needed for a project.

Make `CPACK_DEBIAN_PACKAGE_DESCRIPTION` fallback variable precedence
match CPackRPM behavior as much as possible. This is technically a
breaking change, but the new behavior is more consistent with
expectation anyway.
Closes: #16272
Since commit 14a8d61f (cmMakefile: Port nested error logic away from
cmExecutionStatus) we fail to continue processing function and macro
bodies after non-fatal errors. A non-fatal error should not stop
foreach loops, macro bodies, nested bodies, or the outer script.
Add a test covering these cases, and revert the change to fix them.
Also revert commit 2af853de (cmMakefile: Simplify IssueMessage
implementation) because the assertion it added (which was removed by the
above commit and is restored by reverting it) is incorrect. We do have
code paths that call cmMakefile::IssueMessage with an empty execution
stack, such as in CheckForUnusedVariables's LogUnused call.

Add it to a private source directory that is not installed so that we
can use it for building CMake itself. This will allow it to mature
before being distributed publicly.
The Linux distro we've been using for this is so old that it limits our
ability to import newer third-party software. Until a new machine can
be configured to provide this binary we can simply drop it. Users will
still be able to build from source or use a distro-provided version.
Provide a way for custom commands to inform the ninja build tool about
their implicit dependencies. For now simply make use of the option an
error on other generators.

Add a new SOURCE_SUBDIR option to ExternalProject_Add that allows
specifying the location of the CMakeLists.txt to use as the project root
relative to the SOURCE_DIR.
This is helpful for projects that have unusual layouts, or projects that
provide both a superbuild and project-only build depending on which
CMakeLists.txt is used.
