Issue: #26123
Many `try_compile` and `try_run` calls occur inside check modules
between `message(CHECK_START)` and `message(CHECK_{PASS,FAIL})` pairs.
Add a field to configure log entries to report this context.
Issue: #23200
Since commit 048a02d5bb (ConfigureLog: Log try_compile and try_run
checks, 2022-11-23) we always capture the stdout/stderr for logging.
When cross-compiling, do not require `__TRYRUN_OUTPUT_STD{OUT,ERR}`
variables to be populated just for the logging.
Since commit aa9220d3a0 (try_compile: Add keyword-dispatched signature,
2022-09-02, v3.25.0-rc1~178^2) the `DoNotRunExecutable` code path may be
reached with no single source-file argument. Do not assume it exists.
Fixes: #24295
In order to support multiple log versions without buffering the
entire log, move versioning to the level of individual events.
Multiple versions of an event may then be logged consecutively.
Issue: #23200
Update the `TryCompileCode` signature to allow callers to distinguish
between administrative failures and a compilation failure. Return
results in a structure to which more information can be added later.
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 changes `cmMakefile::AddDefinition` to take a `cm::string_view` as value
argument instead of a `const char *`.
Benefits are:
- `std::string` can be passed to `cmMakefile::AddDefinition` directly without
the `c_str()` plus string length recomputation fallback.
- Lengths of literals passed to `cmMakefile::AddDefinition` can be computed at
compile time.
In various sources uses of `cmMakefile::AddDefinition` are adapted to avoid
`std::string::c_str` calls and the `std::string` is passed directly.
Uses of `cmMakefile::AddDefinition`, where a `nullptr` `const char*` might
be passed to `cmMakefile::AddDefinition` are extended with `nullptr` checks.
