--- Comment #13 from Gilles Caulier <caulier.gilles at gmail.com> ---
The flag is set by digiKAm cmake script like this :

# -- libgphoto2 rules
--------------------------------------------------------------------------

MACRO_OPTIONAL_FIND_PACKAGE(Gphoto2)

if(NOT WIN32 AND GPHOTO2_FOUND)
    # See bug #268267 : digiKam need to be linked to libusb to prevent crash at
gphoto2 init if opencv is linked with libdc1394
    MACRO_OPTIONAL_FIND_PACKAGE(USB)
endif()

if(GPHOTO2_FOUND)
    exec_program(gphoto2-config ARGS --version RETURN_VALUE _return_VALUE
OUTPUT_VARIABLE GPHOTO2_VERSION)
    string(REPLACE "libgphoto2" "" GPHOTO2_VERSION "${GPHOTO2_VERSION}")
    MACRO_ENSURE_VERSION("2.4.0" "${GPHOTO2_VERSION}" VERSION_GPHOTO2)

    if(VERSION_GPHOTO2 AND LIBUSB_FOUND)
        set(GPHOTO2_FOUND true)
    else()
        set(GPHOTO2_FOUND false)
    endif()

    MACRO_ENSURE_VERSION("2.5.0" "${GPHOTO2_VERSION}" VERSION_GPHOTO25)

    if(VERSION_GPHOTO25)
        set(HAVE_GPHOTO25 1)
    else()
        set(HAVE_GPHOTO25 0)
    endif()
endif()

Typically, it run "gphoto2-config --version" CLI tool to check which version is
installed on your system. What give this command on a console ?
