Arha Gatram 79e421b053 ALIAS: Add support for target_* commands
Now that set_property and set_target_properties support ALIAS targets,
we need to extend support to all the target_* type commands that modify
target properties.

Relaxes target_compile_definitions, target_compile_features,
target_compile_options, target_include_directories,
target_link_directories, target_link_libraries, target_link_options,
target_precompile_headers, and target_sources to now accept ALIAS
targets. These commands set properties on the target which the alias
references.

Matthew Woehlke a5a9ec9113 TargetTypes: Extract target-related types to dedicated header
Move some target related enumeration types from `cmStateTypes.h` to a
new header, as these really aren't "state" types. Also, make
`TargetType` a strongly-typed enumeration.

Taylor Sasser d92b6c3e20 CPS: Add Symbolic Components
Adds support for "symbolic" components, which represent feature-level
capabilities of a package that do not correspond to actual build targets.
These are modeled as pseudo-targets, using the INTERFACE type as a base,
and can be queried via:

  get_target_property(... <tgt> "SYMBOLIC")

This enables consumers to declare requirements on optional features
(e.g., SSL support) even when they do not map to concrete targets.

Ben Boeckel 0fb923c460 cmGeneratorExpressionNode: implement COMPILE_ONLY genex
This generator expression is the inverse of `LINK_ONLY` and only coveys
usage requirements for the purposes of compilation. Its intended use is
to avoid needing to export targets that do not have link usage
requirements (e.g., header-only libraries) when used by another target.

It will also be used to represent private usage requirements on exported
C++ module-containing targets in the future.

Eventually there should be logic to collapse nesting of
`$<COMPILE_ONLY>` and `$<LINK_ONLY>` when generating instances of
either. A TODO is left in the code for this case.

Brad King add64399c5 target_link_libraries: Restore LINK_ONLY for multiple static lib dependencies
Since commit c1e812ad4f (target_link_libraries: Improve tolerance of
unquoted generator expressions, 2022-02-15, v3.23.0-rc2~11^2) we
accumulate consecutive non-keyword arguments to recover an unquoted
generator expression as a single entry.  When given multiple consecutive
non-genex library names, the grouping breaks our logic that expects each
entry is either a raw target name or a genex.  Revise the logic to only
accumulate multiple arguments when they end inside a partial genex.

This bug caused `target_link_libraries` to stop wrapping static library
private dependencies in `$<LINK_ONLY:...>` for `INTERFACE_LINK_LIBRARIES`
when multiple consecutive library names are given.  Add a test case
covering that behavior.

Brad King c1e812ad4f target_link_libraries: Improve tolerance of unquoted generator expressions
Prior to commit 1d709ea2f5 (cmGeneratorTarget: Propagate backtraces from
INTERFACE_LINK_LIBRARIES, 2021-12-15, v3.23.0-rc1~228^2), the value of
`INTERFACE_LINK_LIBRARIES` was a single string.  If an unquoted
generator expression passed to `target_link_libraries` contained `;` and
became multiple arguments, they would all accumulate as a single
`;`-separated list in the value of `INTERFACE_LINK_LIBRARIES`.  Since
that commit, each argument to `target_link_libraries` is placed in
`INTERFACE_LINK_LIBRARIES` as a separate entry, as has long been the
case for `LINK_LIBRARIES`. That behavior change broke projects that were
accidentally relying on accumulation in `INTERFACE_LINK_LIBRARIES` to
produce complete generator expressions containing `;`.

Teach `target_link_libraries` to accumulate consecutive non-keyword
arguments into a single entry before placing them in `LINK_LIBRARIES` or
`INTERFACE_LINK_LIBRARIES`.  For example, treat `a b c` as if they were
written as `"a;b;c"`.  This restores the previously accidental support
for unquoted generator expressions in `INTERFACE_LINK_LIBRARIES`, and
also enables it for `LINK_LIBRARIES`.

For now, do not drop the `target_link_libraries` documentation that
recommends quoting generator expressions.  Quoting is still important to
populate `LINK_LIBRARIES` in CMake 3.22 and below, and is also good
practice to keep generator expressions whole.

Since commit daa6d2bc04 (ENH: updated handling of debug and optimized
target link libraries, 2006-11-29, v2.6.0~2471) the ancient
`<lib>_LINK_TYPE` compatibility lookup was done using the name of the
dependent target for which `target_link_libraries` is called, rather
than the name of the library dependency being considered.  This code
probably does nothing.  Remove it.

Brad King f0e67da061 target_link_libraries: Fix out-of-dir linking of a list of targets
In a case like

    target_link_libraries(targetInOtherDir PUBLIC "$<1:a;b>")

then all entries in the list need to be looked up in the caller's
scope.  Previously our `::@(directory-id)` suffix would apply only
to the last entry.  Instead surround the entire entry by a pair
`::@(directory-id);...;::@` so that the `::@` syntax can encode
a directory lookup scope change evaluated as the list is processed.

Sebastian Holtermann 9b334397f5 Source sweep: Use cmStrCat for string concatenation
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)`
