It is often useful to check the found version of a program without
checking whether you can successfully find
`find_program('foo', required: false, version: '>=XXX')`
It makes no sense to specify both:
- install_dir, which overrides the -Dincludedir= builtin option
- subdir, which suffixes the -Dincludedir= builtin option
We've always silently ignored the subdir in this case, which is really
surprising if someone actually passed it and expected it to do
something. We also confusingly didn't say anything in the documentation
about it.
Document that the options are incompatible, and explicitly check to see
if they are both passed -- if so, raise an error message pointing out
that only install_dir should be used.

It would be too difficult and probably a layering violation to give an
interpreter handle to the inner guts of every dependency. What we can do
instead is let every dependency track:
- the Feature checks it can produce,
- the version attribute for when it was implemented
while leaving the interpreter in charge of actually emitting them.
The point of a .use() function is because we don't always have the
information we need to use a feature check, so we allow creating the
feature and then storing it for later use. When implementing location
checks, although it is optional, actually using it violated that design.
Move the location out of the init method for FeatureCheck itself. It
remains compatible with all cases of .single_use(), but fix the rest up.
Use a derived type when passing `subproject` around, so that mypy knows
it's actually a SubProject, not a str. This means that passing anything
other than a handle to the interpreter state's subproject attribute
becomes a type violation, specifically when the order of the *four*
different str arguments is typoed.
We do not want anyone touching this entire directory tree, but due to
the way it was implemented, we only checked if its direct parent was a
subproject violation. This generally worked, unless people tried to add
`subprojects/` as an include directory.
Patch this hole. It now provides the same warning any sandbox violation
does (but is not currently an error, just a "will become an error in the
future").
In commit b30dddd4e5, various refactorings
were done, during which a kwarg got accidentally dropped from the
function that determined part of the log message. As a result, a ':'
suddenly appeared in the log message where none should be.
Example expected output:
Checking if "-Werror=shadow with local shadowing" compiles: YES
What actually happened:
Checking if "-Werror=shadow with local shadowing" : compiles: YES

This has never worked for built/found programs, only for script files.
In commit 2fabd4c7dc scripts learned an
attribute stating which subproject they came from. In commit
3990754bf5 dist scripts learned to run
even from a subproject, and relied on that attribute to know when, in
fact, they came from a subproject.
Unfortunately the original attribute was only set in one half of an
if/else, and the other half returned early with only part of the work
done.
Fixes#9964
In commit 0deab2ee9e we added the ability
to pass a declare_dependency() to any compiler method that accepts
"dependencies", but we never marked the version it is available since.
Fixes#9957
Because we don't want to pass the Interpreter kwargs into the build
layer. This turned out to be a mega commit, as there's really on elegant
way to make this change in an incremental way. On the nice side, mypy
made this change super easy, as nearly all of the calls to
`CustomTarget` are fully type checked!
It also turns out that we're not handling install_tags in custom_target
correctly, since we're not converting the boolean values into Optional
values!
The utility function that processes this for both 'variables' and
'uninstalled_variables' accepts a kwarg for the name of the argument,
but then hardcodes 'variables' in the warning message. This is
misleading.
In commit 06481666f4 this warning got
moved from build.py to the interpreter. Unfortunately it got added to
the wrong function... it is supposed to be part of custom_target and
even mentions this as the feature_name.
Since then, build_always became a KwargInfo and has the deprecated-since
attribute baked into it. But it didn't have the additional message which
it really should have.
Add that message at the same time we remove it from vcs_tag.
