[virt-tools-list] [virt-viewer][PATCH 2/2] tests: Fix VPATH build

[Michal Privoznik]

So test-hotkeys include virt-viewer-app.h which includes
virt-viewer-window.h which includes virt-viewer-display.h which
in turn wants to include virt-viewer-enums.h. But, the enums
header file is generated at build time into builddir not srcdir.
Therefore it may happen if the two are distinct that compiler
fails to find the enums file:

In file included from ../../src/virt-viewer-window.h:29:0,
                 from ../../src/virt-viewer-app.h:28,
                 from ../../tests/test-hotkeys.c:27:
../../src/virt-viewer-display.h:28:31: fatal error: virt-viewer-enums.h: No such file or directory
 #include "virt-viewer-enums.h"
                               ^
compilation terminated.

The fix is to include builddir into paths where header files are
looked for.
