Issue: #26123
The last error may have changed between the original call and the
`GetLastSystemError()` call. Remember the status explicitly and ask it
for its error string.

Since CMake's default compiler flags with MSVC include `-DWIN32` for
historical reasons, a few preprocessor conditions were accidentally
checking for `WIN32` instead of `_WIN32`. The corresponding blocks
were left out when compiling official binaries for `cmake.org` because
we hard-code compiler flags without `-DWIN32`.
Fixes: #22764
This replaces `std::ostringstream`, when it is written to only once.
If the single written argument was numeric, `std::to_string` is used instead.
Otherwise, the single written argument is used directly instead of the
`std::ostringstream::str()` invocation.
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)`

Enables the clang-tidy test performance-inefficient-string-concatenation
and replaces all inefficient string concatenations with `cmStrCat`.
Closes: #19555
Replace the members for the Makefile and the Error with a
cmExecutionStatus. Re-implement GetMakefile and SetError based on that.
Both functions should be called directly on the cmExecutionStatus that is
passed to InitialPass. This will help us make all Commands immutable and
remove the need for cloning.
