This would make it harder to parse an option to mesonconf such
as -Dfoo:bar:baz:fun=value since it could mean either of these:
* For subproject 'foo:bar:baz', set the option 'fun' to 'value'
* For subproject 'foo:bar', an invalid option 'baz:fun' was set
To differentiate between these two we'd need to create the list of
subprojects first and then parse their options later, which
complicates the parsing quite a bit.
This means replacing @PLAINNAME@ and @BASENAME@ in the outputs. This is
the same feature as generator().
This is only allowed when there is only one input file for obvious
reasons + failing test for this.
With the exception of things like sysconfdir (/etc), every other
installation directory option must be inside the prefix.
Also move the prefix checks to coredata.py since prefix can also be set
from inside project() with default_options and via mesonconf. Earlier
you could set prefix to a relative path that way.
This also allows us to return consistent values for get_option('xxxdir')
regardless of whether relative paths are passed or absolute paths are
passed while setting options on the command-line, via mesonconf, or via
default_options in project(). Now the returned path will *always* be
relative to the prefix.
Includes a unit test for this, and a failing test.
Closes#1299
This is already how it should've been, but:
a) The test for this was wrong since Dependency is a base class for all
dependencies and isinstance on an InternalDependency will also be true
b) Internal dependencies can't ever be used here anyway because compiler
checks are always run at configure time and internal dependencies are
only built after that.
Sometimes we want to restrict the acceptable versions to a list of
versions, or a smallest-version + largest-version, or both. For
instance, GStreamer's opencv plugin is only compatible with
3.1.0 >= opencv >= 2.3.0
If first checking for a dependency as not-required, and then later
checking for the same dependency again as required, we would not
error out saying the dependency is missing, but just silently
re-use the cached dependency object from the first check and then
likely fail at build time if the dependency is not actually there.
With test case.
Fixes#964.
At the same time, this also adds a bunch of tests that document and keep
track of how we expect quoting to pass through via Ninja to the
compiler.
We need at least Ninja 1.6.0 for this.

On MSVC, shared libraries only export symbols that have been explicitly exported
either as part of the symbol prototype or via a module definitions file.
On compilers other than MSVC, all symbols are exported in the shared library by
default and the format for the list of symbols to export is different, so this
is only used with the VisualStudio compiler.
The module defs file path can either be relative to the current source directory
or an absolute path using meson.source_root() + '/some/path'
