            Bug ID: 183896
           Summary: [WPE][GTK] Build failure when ENABLE_VIDEO,
                    ENABLE_WEB_AUDIO and ENABLE_XSLT are disabled
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit WPE
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com
                CC: bugs-noreply at webkitgtk.org

This can be reproduced with the following commands:

   % cd path/to/WebKit
   % mkdir build && cd $_
   % cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DDEVELOPER_MODE=ON \
           -DCMAKE_INSTALL_PREFIX=$JHENV -DENABLE_VIDEO=OFF \
           -DENABLE_WEB_AUDIO=OFF -DENABLE_XSLT=OFF -DPORT=WPE \
           -G Ninja ..
   % ninja

The build error is as follows, I think that DEVELOPER_MODE is not really
the culprit:
