[Slackbuilds-users] call for digikam tester

[Larry Hajali]

Hi Willy,

I'm able to reproduce the error in a VM when I only have ffmpeg, opencv and
lensfun installed.  You are correct in you assumption that when lensfun is
installed that liblqr is also needed.

In the file digikam-3.5.0/core/cmake/modules/FindLqr-1.cmake, if the
variables LQR-1_LIBRARY and LQR-1_INCLUDE_DIR are defined then the GLIB2
package is searched for.  If GLIB2_FOUND is set, then both of the libraries
(ie. liblqr and lensfun) are linked to libdigikamcore.so library as defined
in the file dikigam-3.5.0/core/digikam/CMakeLists.txt using this block of
code.

# For Contents Aware Resizer and Lens auto-correction tools.
IF(GLIB2_FOUND)
    TARGET_LINK_LIBRARIES(digikamcore ${GLIB2_LIBRARIES} ${liblqr_LIBS}
${liblensfun_LIBS})
ENDIF(GLIB2_FOUND)

So the way I see it, both liblqr and lensfun are required for proper
linking, otherwise, you get the undefined references for lensfun.
