cmGeneratorExpression::Evaluate is a shortcut when only the evaluated string is
needed or an instance of cmCompiledGeneratorExpression cannot be cached.
Fixes: #19686
Simplify by re-ordering parameters of cmCompiledGeneratorExpression::Evaluate
so that frequently used parameters are before less frequently used parameters.
This allows with little extra arguments to get rid of one Evaluate overload,
which makes it easier to implement the cmGeneratorExpression::Evaluate utility.
The latter would otherwise need four overloads.
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.
Object libraries do not link and therefore do not need to consider the
object files from "linked" dependencies on other object libraries.
This was an oversight in commit 57538224d0 (objlib: Link object-files
from `OBJECT` libraries, 2017-12-14, v3.12.0-rc1~419^2~2).
Fixes: #19744

Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
Target-level dependencies to utility targets are added from another target if
the other target requires a byproduct of the utility target or if it requires a
byproduct of PRE_BUILD, PRE_LINK, or POST_BUILD build events of a target.
Issue: #19005
Set the MinTypeNameLength option to an impossibly high value in order
to limit the diagnostics to iterators. Leave new expressions and cast
expressions for later.
This is better than doing CopyFileIfDifferent() followed by RemoveFile() in
two ways:
- it is more efficient, as it avoids disk I/O for the data, even if the
files here are usually small
- it is atomic, so an abort during the copy will not leave a destination file
with partial data behind
GetOrDetermineLanguage:
- Read the property if available
- Determine the Language using the file extension
Fix all usage of the non-const member in the repository.
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)`
This replaces invocations of
- `cmSystemTools::IsInternallyOn` with `cmIsInternallyOn`
- `cmSystemTools::IsNOTFOUND` with `cmIsNOTFOUND`
- `cmSystemTools::IsOn` with `cmIsOn`
- `cmSystemTools::IsOff` with `cmIsOff`
This adds the following functions to `cmStringAlgorithms`:
- `cmIsSpace`
- `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`)
- `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`)
- `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to
accept `cm::string_view`)
Under CMP0022 NEW behavior, the link interface is explicit even if there
are no public dependencies (`INTERFACE_LINK_LIBRARIES` is not set).
Mark it as such to activate our tracking of private runtime dependencies
of shared libraries for generation of `-rpath-link` flags.
