Some commands on Windows do not understand forward slash paths and
require backslashes. In order to help projects generate shell
invocations of such commands, provide a generator expression to convert
paths to the shell-preferred path format for the current generator.
This will allow custom commands to generate paths the same way CMake
does for compiler command invocations.
Extend sentences in other documentation linking to this manual to
say that it has a list of supported compilers.

Update the wording of some examples to avoid long lines in code blocks.
Otherwise the formatted documentation can exceed certain column width
limitations.
Previously this generator expression was used internally by the
target_link_libraries command to honor private linking requirements of
static libraries in their INTERFACE_LINK_LIBRARIES. Remove the check
that limits $<LINK_ONLY> to this use case to make it available for
project code to use too.
In the cmake-generator-expressions(7) manual, link to the variables
that correspond to the PLATFORM_ID, C_COMPILER_ID, CXX_COMPILER_ID,
C_COMPILER_VERSION, and CXX_COMPILER_VERSION generator expressions.
Link to it from the documentation of related properties, variables
and commands.
Extend the cmake-developer(7) documentation with notes on
extending feature support for compilers.
Allow setting build properties based on the features available
for a target. The availability of features is determined at
generate-time by evaluating the link implementation.
Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation. This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc. To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.
This commit may be reverted in the future if a solution to the
above difference is implemented.
This is consistent with other similar expressions such as PLATFORM_ID,
and makes the CONFIGURATION expression obsolete.
Fix an off-by-one error in
GeneratorExpressionContent::EvaluateParameters exposed by a unit test.
Remove the test for 'bad' nullary use of $<CONFIG>.
Add a unit test to verify that $<CONFIG> and $<CONFIGURATION> have
the same value.
Use definition lists instead of a preformatted block to enumerate
the genex documentation.
Consistently capitalize the description.
Use ``...`` to format genex parameters in the description.
Turn references to commands into links.
Add high level documentation about the motivation for generator
expressions.
Regroup expressions into subsections for different genex types. Add
a high-level description and example of the expressions in each
section.
Explode the documentation for filesystem artifacts, instead of only
referring to the variations.
Add the man page description line as explicit markup at the top of each
Help/manual/*.rst file and scan it from conf.py to automatically
generate the man_pages Sphinx configuration value. This reduces the
number of places that need to be changed when a new manual is added.
Generator expressions are supported in many places and are a distinct
concept worthy of their own manual page. The old builtin documentation
was previously represented by preprocessor macros to generate it into
each place that supports them. Factor out the duplicate content into a
dedicated cmake-generator-expressions manual page and reference it from
each original location.
