Below I will describe all my actions (I have a PC with Windows 10):
1. Installed Oracle Virtual Box.
2. Installed Ubuntu 22.04.
3. Cloned the Webkit project (using the command `git clone https://github.com/WebKit/WebKit.git WebKit`).
4. In Terminal I used `cd WebKit` and after that `cmake -DPORT=WPE -DCMAKE_BUILD_TYPE=RelWithDebInfo -GNinja` (there were a lot of errors about missing libraries after this command).
5. Installed all libraries (more than 15).
6. Used the `cmake -DPORT=WPE -DCMAKE_BUILD_TYPE=RelWithDebInfo -GNinja` command again (no errors).
7. After that, I used the `ninja` command and an error occurred.

I need to install a WPE browser and further automate testing of an application that is created for this browser using Python Selenium WebDriver.

Hi, this doesn't look like a WebKit bug. If you use -DENABLE_MINIBROWSER=ON then you should get MiniBrowser which might be good enough for your testing. For something better than that, try https://github.com/Igalia/cog.

Oh sorry, I see you failed to build WebKit altogether. Please, post the actual error message here, don't just post a screenshot. Make sure to install the dev package for gobject-introspection. This is probably actually a WebKit bug, because we should check for this initially when running cmake and fail the build with a nice error message if missing, and not fail later with this confusing message when running ninja.

[Michael Catanzaro]

Probably something wrong inside FindGI.cmake, but it's complicated and I've never understood how find modules work.

The --include=Foo-X.Y flags will try to search for the file Foo-X.Y.gir
in the default search path, typically /usr/share/gir-1.0 -- there should
be Ubuntu packages which provide the needed files. For example in Arch
Linux one can see that the .gir files are provided either by their own
package, or gobject-introspection for the base .gir files:

  % pacman -Qo /usr/share/gir-1.0/GObject-2.0.gir      
/usr/share/gir-1.0/GObject-2.0.gir is owned by gobject-introspection 1.76.0-1
  % pacman -Qo /usr/share/gir-1.0/Gtk-3.0.gir  
/usr/share/gir-1.0/Gtk-3.0.gir is owned by gtk3 1:3.24.37-1

Checking the contents of the gobject-introspection package, it does not
include any .gir files, see:

  https://packages.ubuntu.com/focal/amd64/gobject-introspection/filelist

Searching in package contents for files ending in .gir returns no results
which would contain the GObject-2.0.gir file:

  https://packages.ubuntu.com/search?suite=focal&arch=any&searchon=contents&keywords=.gir

I haven't checked other Ubuntu versions, but at least for 20.04LTS it looks
like there is a packaging bug there.

I would expect it to be provided by gobject-introspection-dev or a similarly-named package. In Fedora it's provided by gobject-introspection-devel.

Found it, the package is “libgirepository1.0-dev”:

Dmytro: Could you try installing this package? I am positive it will
fix your build issue. If it does not, please reopen the issue and let
us know.

Still, we should be able to detect missing g-i dependencies at cmake time rather than failing later on at build time. You want to know whether something is missing upfront.
