Since `build_always` also adds a target to the set of default targets,
this option is marked deprecated in favour of the new option
`build_always_stale`.
`build_always_stale` *only* marks the target to be always considered out
of date, but does *not* add it to the set of default targets.
The old behaviour can still be achieved by combining
`build_always_stale` with `build_by_default`.
fixes#1942
This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.
We say 'different dependencies support different values for this', but
nowhere document what values are supported, so the only way to find these
out is to read the source, or guess. Make a start at doing that.
Refine #3277
According to what I read on the internet, on OSX, both MH_BUNDLE (module)
and MH_DYLIB (shared library) can be dynamically loaded using dlopen(), but
it is not possible to link against MH_BUNDLE as if they were shared
libraries.
Metion this as an issue in the documentation.
Emitting a warning, and then going on to fail during the build with
mysterious errors in symbolextractor isn't very helpful, so make attempting
this an error on OSX.
Add a test for that.

When using binutils's windres, we can instruct it to invoke the preprocessor
in such a way that it writes a depfile, so that dependencies on #included
files are automatically tracked.
Not implemented for MSVC tools, so skip testing it in that case.
Since f3ff8fe6 (0.39.0), this has a common implementation with the same
substitution in generators, but I think they existed earlier.
@BASENAME@ is used internally by the custom target generated by
windows.compile_resources()
Expose depend_files: from the custom_target this creates.
This is the change suggested in #2815, with tests and documentation added.
Fixes#2789 (duplicate #2830)
* docs/reference-manual: link to references tables
Currently the reference manual entries for *machine.cpu_family() and
*machine.system() have incomplete (and wrong) information. Rather than
continue to duplicate this information just link to the reference
tables.
* docs/Reference-manual: fix link target
The IDs in hotdoc are always lowered, so this pointed to the right page,
but didn't go to the heading.
* docs/Reference-manual: link compiler.get_id directly to tables
Currently it goes round about to an entry that doesn't add much
information and points to the reference table. Instead just point to the
reference table.
Mention that the dependency name will also be searched for as a framework on
OSX.
Note that additional dependency-specific keywords may be used by custom
dependency lookup.
PR #1852 only adds mention of this to the release note.
I think it's useful to have a list of all dependency names which are treated
specifically in Dependency.md, so add 'thread' and 'openmp'.
