This gives a clearer output when the dependency is not required or has a
fallback subproject otherwise the user is left wondering why the optional
dependency wasn't used or why the fallback subproject is being used.
Just exit immediately when there's no pkg-config file found instead of putting
everything else in a huge 'else:'. Much clearer and avoids one level of
indentation.
No code changes accompany this.
Trivially correct typo fix. Didn't actually break anything because the
fallback is libdir anyway, and we always install static libraries to
libdir.
Pointed out by Zhe Wang (0x1997).
The Meson script is not always in $scriptdir/../../ -- for instance if
installed with pip on Windows, the scriptdir is in:
C:/Python35/Lib/site-packages/meson-0.33.0.dev1-py3.5.egg/mesonbuild/scripts
and the meson.py script is in:
C:/Python35/Scripts
So, let's save the path available as Environment().meson_script_file
into the coredata.dat private file and use that to invoke Meson when
doing regen.
Also, let's fetch the backend that was used from the coredata too
instead of hard-coding vs2010.
Both these were causing a hard failure while doing regen with msbuild or
visual studio.
Otherwise we'll mark the build directory as successfully configured even
if there's an error while doing the actual generation.

The first file might be a header file, in which case this test will
fail, so check all the files till a match is found instead.
Also remove duplicate and incorrect can_compile check. It just checks
the suffix and we already check that above.
It should always be passed build_to_src otherwise the path for generated
files will always be wrong. Passing the vcxproj path as the build_to_src
only works for files in the source tree.
These need to be set via XML tags and not passed directly as
AdditionalOptions. Otherwise the project will end up with inconsistent
compiler options and the build will fail.
Since Meson internals assume that these will be set via a command-line
invocation, we need to detect the presence of various flags in
buildtype_args and buildtype_link_args and set the correct options in
the vcxproj file.
Note that this means different configurations (debug/release/etc) cannot
be enumerated in the vcxproj/sln files and chosen by the user at build
time because arbitrary build characteristics can depend on that. The
only way to support that is by doing a full parse and conversion of
Meson build files (for all build options) to vcxproj files.
The link arguments for each dependency are split into these three and
added to the vcxproj file. Without this targets cannot find the external
dependencies.
