[libcamera-devel] [PATCH v5 07/10] libcamera: make libdl optional when provided

[nicholas at rothemail.net]

From: Nicholas Roth <nicholas at rothemail.net>

Currently, libdl is always required. Sometimes, the C++ runtime includes
a dynamic loader, which is the case for Android. Additionally, Android
11 does not have libdl. This fix allows libcamera to build on Android.
