Fix 'not founded' message for packages with another name for
specific configurations instead of just 'library'.

When building for iOS, the Qt binaries only contain static libraries
and headers. No framework.
With this, Meson can successfully compile and link to Qt on iOS
Instead of only doing a naive filesystem search, also run the linker
so that it can tell us whether the -F path specified actually contains
the framework we're looking for.
Unfortunately, `extraframework` searching is still not 100% correct in
the case when since we want to search in either /Library/Frameworks or
in /System/Library/Frameworks but not in both. The -Z flag disables
searching in those prefixes and would in theory allow this, but then
you cannot force the linker to look in those by manually adding -F
args, so that doesn't work.
Also add a test for it. In the process, also remove an overly-zealous
try..except statement that was catching *all* exceptions, not just
expected ones, which was masking programming errors.
.get_command() will return None when it's not found, so there's no
point trying to print that. Print self.name instead, which is what
we tried to search for.
First, I noticed there was a dangling use of now-removed cross_info in
the CMake lookup. No tests had caught this, but it means that CMake deps
were totally broken. [It also meant that CMake could not be specified
from a native file.]
In a previous of mine PR which removed cross_info, I overhauled finding
pkg-config a bit so that the native and cross paths were shared. I
noticed that the CMake code greatly resembled the pkg-config code, so I
set about fixing it to match.
I then realized I could refactor things further, separating caching,
finding alternatives, and validating them, while also making the
validations less duplicated. So I ended up changing pkg config lookup a
lot too (and CMake again, to keep matching).
Overall, I think I have the proper ideom for tool lookup now, repated in
two places. I think it would make sense next to share this logic between
these two, compilers, static linkers, and any other tool similarly
specifiable. Either the `BinaryTable` class in environment.py, or a new
class for `Compiler` and friends to subclass, would be good candidates
for this.
In recent change, dependency('foo') does not return a not-found
PkgConfigDependency any more, but a NotFoundDependency object. This
creates a regression in gst-build that does
dependency('foo').get_partial_dependency() causing Meson to raise an
exception.
The returned not-found object can be from any type because we were
returning the first of the failed attempts. It also can happen that we
don't have any dependency object in which case we should just return
NotFoundDependency() object as well instead of raising an exception.
That exception was happening before, but dependency_impl() was
calling find_external_dependency() in a try block so it was hidden.
When req_version is None (e.g. pcap-config case) it gets printed in the
logs.
Take this opportunity to reformat the message to look more like
ExternalProgram messages.
When trying to cross-compile mesa on an aarch64 system, I noticed some
strange behavior. Meson would only ever find the wayland-scanner binary
in my host machine's sysroot (/mnt/amethyst):
Native dependency wayland-scanner found: YES 1.16.0
Program /mnt/amethyst/usr/bin/wayland-scanner found: YES (/mnt/amethyst/usr/bin/wayland-scanner)
It should be finding /usr/bin/wayland-scanner instead, since the
wayland-scanner dependency is created as native. On closer inspection,
it turned out that meson was ignoring the native argument passed to
dependency(), and wuld always use the pkgconfig binary specified in my
toolchain instead of the native one (/usr/bin/pkg-config):
Native dependency wayland-scanner found: YES 1.16.0
Called `/home/lyudess/Projects/panfrost/scripts/amethyst-pkg-config
--variable=wayland_scanner wayland-scanner` -> 0
Turns out that if we create a dependency() object with native:false, we
end up caching the pkg-config path for the host machine in
PkgConfigDependency.class_pkgbin, instead of the build machine's
pkg-config path. This results causing in all pkg-config invocations for
dependency() objects to use the host machine's pkg-config binary,
regardless of whether or not 'native: true' was specified when the
dependency() object was instantiated.
So, fix this by never setting PkgConfigDependency.class_pkgbin for cross
dependency() objects. Also, add some test cases for this. Since
triggering this bug can be avoided by creating a dependency() objects
with native:true before creating any with native:false, we make sure
that our test has two modes: one where it starts with a native
dependency first, and another where it starts with a cross dependency
first.
As a final note here: We currently skip this test on windows, because
windows doesn't support directly executing python scripts as
executables: something that we need in order to point pkgconfig to a
wrapper script that sets the PKG_CONFIG_LIBDIR env appropriately before
calling pkg-config.
