Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that
the toolchain has no notion of lanuage standard levels. In this case
the <LANG>_STANDARD[_REQUIRED] properties will have no effect.
Update the RunCMake.CompileFeatures test to exclude the
LinkImplementationFeatureCycle test when there is no standard default.
It can never fail because no use of specific features will adjust the
CXX_STANDARD level required for any target since the standard levels
have no meaning in this case.
The use of FeatureSummary inside a find module is not a convention
yet used by upstream CMake modules. Drop the example from the
documentation about how to write find modules. If in the future
we add use of FeatureSummary to many of the upstream find modules
then this example can be restored as part of establishing the
convention.
An IMPORTED target in either type of package can equally depend on
an IMPORTED target in a Find module, which must be found as a
dependency, which is presumably the problem being implied. This is
not a distinction of creating an IMPORTED target in a Find module.
Update the wording of some examples to avoid long lines in code blocks.
Otherwise the formatted documentation can exceed certain column width
limitations.
Explicitly specify the sequence of underline characters we use in the
CMake documentation. It is the same sequence as that suggested in the
Sphinx documentation, but we have our own descriptions.
This is the convention suggested in the Sphinx documentation and is
already used in several other places in the CMake documentation.
Update a few places where we were using other characters.
Teach set_property and get_property an "INSTALL" property type to be
associated with install-tree file paths. Make the properties available
to CPack for use during packaging. Add a "prop_inst" Sphinx domain
object type for documentation of such properties.
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.
As well as the traditional variables, providing imported targets is
suggested, and the relative advantages and disadvantages briefly
discussed.
A mini-tutorial walking through creating a simple find module is
provided.
This changes the recommended version variable from Foo_VERSION_STRING to
Foo_VERSION, because there is really no need to have different variable
names for package version files vs. find modules. It notes the old
variable name, though, and suggests setting it for compatibility.
The cmake-language.7 manual now documents comment syntax. Reference it
from cmake-developer.7 when discussing how to add comment-enclosed
documentation to modules.
Simply print out the lines as normal paragraph text. Teach the
CMakeLib.testRST test to cover this syntax. Update the
cmake-developer.7 manual to document support for the directives.
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.
When scanning CMake module files for .rst comments, recognize
bracket comments starting in ".rst:" too. For example:
#[[.rst:
Include the bracket comment content terminated by the closing bracket.
Exclude the line containing the bracket if it starts in "#".
Teach the CMakeLib.testRST test to cover multiple bracket lengths
and ending brackets on lines with and without "#".
Update the cmake-developer.7 manual to document the bracket-comment
syntax for .rst documentation.
The cmRST implementation and the list of capabilities documented in the
cmake-developer.7 manual must be kept in sync. Add a note to each file
to reference the other.
Document how CMake uses reStructuredText to provide the help manuals.
Cover supported inline markup and directives, the CMake Domain in
Sphinx, and cross-reference syntax.
Add "Module Documentation" and "Find Modules" subsections. Add to
Modules/readme.txt a textual reference to the cmake-developer.7 manual
and, while at it, fix the wiki URL domain.
Convert the content moved from Modules/readme.txt to valid
reStructuredText markup. Mainly, convert the lists of variables to
definition lists, wrap long lines in paragraph text, and add literal
block markup and indentation.
Move all content from Modules/readme.txt except for the link to the
module maintainers wiki page into "Help/manual/cmake-developer.7.rst".
This produces some invalid reStructuredText markup to be fixed in a
future commit.
