properties LINK_OPTIONS and INTERFACE_LINK_OPTIONS are propagated
to the device link step.
To control which options are selected for normal link and device link steps,
the $<DEVICE_LINK> and $<HOST_LINK> generator expressions can be used.

Since commit fbf7a92975 (Makefile: Handle '#' in COMPILE_OPTIONS,
2014-08-12, v3.1.0-rc1~174^2) we escape `#` as `\#` in `flags.make`
variable assignments so that they are not treated as a comment.
Windows-style make tools like NMake do not interpret backslashes
in that way. Other means will be needed to handle `#` in contexts
where it is even possible. The test suite is not covering this
for NMake anyway, and actually has a workaround in `Tests/TryCompile`
for the old behavior, which we can now update.
The `std::endl` manupulator, except inserting `\n` character, also
performs `os.flush()`, which may leads to undesired effects (like
disk I/O in the middle of forming data strings). For the
`std::stringstream` it also has no meaning.
Since commit f6f4eb0907 (clang-tidy: Add driver mode argument,
2020-01-19) the `clang-tidy` tool rejects the new option:
Unknown command line argument '--driver-mode=g++'.
This is because we are adding the flag before the main compiler
command-line. Encode it with `--extra-arg-before=` so that `clang-tidy`
knows it is supposed to be part of the compiler command.

`clang-tidy` does not infer driver mode if it is not provided with a
JSON compilation database. This is exactly the way cmake launches it.
Hence clang-tidy will only use the default driver mode. Add an explicit
driver mode argument to avoid this.
Teach the Makefile generator to scan the implicit dependencies of PCH
creation. When a header named by `target_precompile_headers` changes
the corresponding PCH must be rebuilt and all consumers recompiled.

cmGeneratorExpression::Evaluate is a shortcut when only the evaluated string is
needed or an instance of cmCompiledGeneratorExpression cannot be cached.
Fixes: #19686
The quiet flag is false for all but one call to Evaluate. Make the quiet flag
a setter of cmCompiledGeneratorExpression to be able to remove it from the
Evaluate function signature.
Evaluate and expand generator expressions in byproducts of custom commands.
Note that it is still not possible to use generator expressions in byproducts
of the commands `add_custom_command` and `add_custom_target`. These commands
still reject the input. This is a preparation step for OUTPUT generator
expression support.

Fix the order of logic added by commit 7740ccd1a4 (ENH: some cleanup of
the makefile generator, 2006-02-14, v2.4.0~517) to check for allocation
failure ('new' returns null) before using the pointer.
Issue: #19610
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
This replaces invocations of
- `cmSystemTools::IsInternallyOn` with `cmIsInternallyOn`
- `cmSystemTools::IsNOTFOUND` with `cmIsNOTFOUND`
- `cmSystemTools::IsOn` with `cmIsOn`
- `cmSystemTools::IsOff` with `cmIsOff`
