I have just tried compiling tensorflow-lite from master, and it was
successful. Before digging any further, have you tried a "bitbake -c
cleanall tensorflow-lite" and then try to build again, without changing
the recipe?

Regarding libcamera-apps, that's a bit more involved. Meson is trying to
find tflite by cmake and pkg-config, but the tflite recipe has neither.
As a good news, libcamera-apps devs have added an option to find tflite
without cmake and pkg-config file just lately, however...

1. It needs to be added to meta-rpi. This feature was added in 1.9.0,
but the layer ships 1.4.2-ish. PR: [1]
2. Updated libcamera-apps need a newer libcamera, which needs to be
updated in meta-oe. Patch: [2]
3. Beside the above, it looks like that tensorflow-lite recipe doesn't
package headers. Patch: [3]
4. libcamera-apps is looking for "libtensorflow-lite.so", but
meta-tensorflow installs "libtensorflowlite.so" (without a hyphen). This
needs some investigation who is right, who is wrong - maybe no one is
wrong, but I have no idea at this moment. As an quick and ugly "just
make it hekin' work" solution you can work around it locally by adding a
bbappend to tflite, with the following content:

do_install:append(){
  ln -s libtensorflowlite.so ${D}${libdir}/libtensorflow-lite.so
}

If you apply the linked patches, I believe you should be able to compile
libcamera-apps with tensorflow lite. Though before working on
libcamera-apps, you should get to the bottom of your issue with
tensorflow-lite itself.

HTH.
