There are no images stored by the test binaries.

It sounds like you are expecting to run the test-utilitys such as 'cam'
or 'qcam'.

You can find those under:

 ./build/src/cam/cam

and

 ./build/src/qcam/qcam

If you have a graphical window environment, try running qcam first to
see if it presents any images.

Or check to see if any cameras are available to libcamera using:

 ./build/src/cam/cam -l

On my system this produces:

> libcamera$ ./build/src/cam/cam -l
> [33:14:01.618700292] [582376]  INFO IPAManager ipa_manager.cpp:136 libcamera is not installed. Adding '/home/linuxembedded/iob/libcamera/libcamera/build/src/ipa' to the IPA search path
