How to compile ui.xml to ui.h

[Pang Dawei]

Hi,all
    I modified thunar-window-ui.xml, and need to thunar-window-ui.h.
    I check the source code of  thunar-window-ui.h. I found that is
"automatically generated from ./thunar-window-ui.xml".
But I run the make command, the thunar-window-ui.h cannot be generated.
    Can you help me how can I compile the thunar-window-ui.xml to
thunar-window-ui.h.
    Thank you very much.
