Previously when CMAKE_CROSSCOMPILING was ON we'd end up not setting the target
directory if the non-scattered one didn't exist.
Fix this by assuming a scattered installation if the target directory isn't set
after the crosscompiling logic.
This is the same fix as commit 2c0d5d01ee (CUDA: Support scattered
installations when crosscompiling with Clang, 2020-09-14).
Adds a set of sub commands to the string command for parsing JSON, the
JSON commands are: GET, TYPE, MEMBER, LENGTH, REMOVE, SET, and EQUAL.
Closes: #19501
`ExternalProject_Add_StepTargets` and `INDEPENDENT_STEP_TARGETS` have
some limitations and lack some sanity checks. They can cause confusing
build systems to be generated. The basic problems are:
* The notion of step independence is attached to the step target
rather than the step itself.
* The custom commands implementing the steps are duplicated in the
step targets and the primary targets. This can cause races.
It is also incompatible with the Xcode "new build system".
Fix this by introducing policy CMP0114 to change the way step target
dependencies are handled. Define independence from external
dependencies as a property of each individual step regardless of whether
there is a target for it. Add dependencies among the primary target and
the step targets such that each custom command only appears in one
target. When some steps are disconnected from the primary target, add
step targets for the steps commonly depended upon so that there is a
place to hold their custom commands uniquely.

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.
This may break existing projects that do not properly mark non-created
outputs with the `SYMBOLIC` property. Previously a chain of two custom
commands whose intermediate dependency is not created would put both
commands in a dependent project's Makefile even if the first command is
also in its dependency's Makefile. The first command would run twice
but the build would work. Now the second command needs an explicit
`SYMBOLIC` mark on its input to tell CMake that it is not expected to
exist. To maintain compatibility with projects that left out the mark,
add a policy activating the behavior.
Adds PCH_INSTANTIATE_TEMPLATES target property for enabling template
instantiation in precompiled headers.
Enabled by default. Currently only supported for Clang 11 and newer.
Implements #21133.

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.

OBJECT and STATIC libraries (framework or non-framework) do not use
this build phase. Not all items to be linked use this build phase either.

If an user specified a host compiler we should fail if we are unable to perform
compiler detection with it.
Previously we would try without and likely succeed and continue. Then we'd fail
during ABI detection and compiler testing since we'd still try to use it.
This is particularly problematic when crosscompiling since we extract the host
linker from the compiler detection link line. This would result in the wrong
host linker being used and a linking error due to architecture mismatch during
ABI detection where other necessary flags may already be present to make the
host compiler work. See #21076 for an example.
Fix this by adding CMAKE_<LANG>_COMPILER_ID_REQUIRE_SUCCESS to
CMakeDetermineCompilerId, which throws a fatal error if executing the compiler
results in a non-zero exit code.
Fixes#21120.
