These paths are now generated similar to
NinjaBackend.generate_single_compile where IncludeDirs create includes
of both the build directory path and the source directory path.
This also fixes a bug with include_directories, where the path string
supplied to the IncludeDirs initializer was used for the search path,
instead of the actual location to which it referred. Often, this was a
'.', and not a really useful path.
the pkgconfig module automatically specified to install the
pkgconfig file to {libdir}/pkgconfig. Default settings in meson
already include multiarch-directories like x86_64-gnu-linux into
the libdir. pkgconfig usually does not check inside multiarch-dirs
for any pkgconfig-files.
to make this a bit more flexible, this commit introduces the
install_dir attribute for pkgconfig.generate. if it is set, the
default install path will be overridden by the users input
The extra arguments are typically used to specified the location of
installed API references that gtk-doc can use to create cross links
for symbols.
Fixes#555
There are use case where one may want to specify --sourcedir option
multiple times to glib-compile-resources, which will look for
resources in every specified directory.
By doing this, we also need to get rid of the manual GResource XML
parsing and we opted to use the glib-compile-resources command with
the --generate-dependencies option. This command will solve the
multiple source_dir case for us.
