In QEMU a single set of source files is built against many different
configurations in order to generate many executable. Each executable
includes a different but overlapping subset of the source files; some
of the files are compiled separately for each output, others are
compiled just once.
Using Makefiles, this is achieved with a complicated mechanism involving
a combination of non-recursive and recursive make; Meson can do better,
but because there are hundreds of such conditional rules, it's important
to keep meson.build files brief and easy to follow. Therefore, this
commit adds a new module to satisfy this use case while preserving
Meson's declarative nature.
Configurations are mapped to a configuration_data object, and a new
"source set" object is used to store all the rules, and then retrieve
the desired set of sources together with their dependencies.
The test case shows how extract_objects can be used to satisfy both
cases, i.e. when the object files are shared across targets and when
they have to be separate. In the real-world case, a project would use
two source set objects for the two cases and then do
"executable(..., sources: ... , objects: ...)". The next commit
adds such an example.
This new cmake module allows to generate cmake package files. This may ease the
porting for cmake projects that are exporting cmake package informations for other
depending projects. The module uses as much as possible the templates provided by
the cmake installation (and so cmake needs to be installed).
Document what waring_level 1,2,3 means.
Test if markdown files are in sitemap
Add Builtin-options.md to sitemap.txt
Builtin-options.md:
Fix tables in Builtin-options.md
Add documentation for warning options
Added more options to doc
General documentation:
Add link to Builtin-options
Remove obsolete file
Testing:
Add function test_markdown_files_in_sitemap.
Checks if each markdown file is contained in sitemap.txt
This allows us to more easily have the documentation in sync with
the source code as people will have to document new features etc
right at the time where they implement it.
