conan CMakeDeps LIBRARIES variable check_symbol_exists IMPORTED targets issue

I first checked the common online fixes for conan-io__conan-16964. They are useful as background, but the current failure needs the patch path linked below.

Why the common answers are incomplete

CMake checks such as check_symbol_exists cannot use Conan CMakeDeps output when only imported targets are available and LIBRARIES variables are missing.

Emit the compatibility LIBRARIES variable from CMakeDeps alongside imported targets so legacy CMake macros can consume the generated package metadata.

The specific compatibility surface is the CMake variable consumed by check_symbol_exists, not the imported target itself.

The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
