Tested on RPi3/RPi4 with linux-5.4.45-v7l kernel and updated
rpi-firmware package, Qt-5.14.2:

First try:

	$ qcam -platform linuxfb -c ov5647

With the following patch libcamera is forced to believe it is running
in a installed environment:

diff --git a/src/libcamera/utils.cpp b/src/libcamera/utils.cpp
index d55338f..4ff9dac 100644
--- a/src/libcamera/utils.cpp
+++ b/src/libcamera/utils.cpp

 	 */
 	for (const ElfW(Dyn) *dyn = _DYNAMIC; dyn->d_tag != DT_NULL; ++dyn) {
-		if (dyn->d_tag == DT_RUNPATH || dyn->d_tag == DT_RPATH)
+		if (dyn->d_tag == DT_RUNPATH || dyn->d_tag == DT_RPATH) {
+			printf("XXXXX - dyn->d_un.d_ptr: %s\n", (char*)dyn->d_un.d_ptr);
 			return false;
+		}
 	}
-
+#endif
 	return true;
 }
 

Maybe this is because of the buildroot local meson patch ([1]), leading
to an empty (but not absent) RPATH?

With this patch applied, next try:

Maybe related to the buildroot finalize and/or sanitizing RPATH in target tree
step (and/or strip after install with BR2_ENABLE_DEBUG=y/BR2_STRIP_strip=y
enabled)?

Final run (success):
