## @brief Construct a platform-appropriate shared-library filename hint.
## @param[out] out_var Variable name to set in the parent scope with the
##            constructed name.
## @param[in] lib_name Base library name without prefix/suffix (for
##            example: avcodec).
## @param[in] prefix_path Optional directory prefix to prepend before the
##            library filename (no trailing separator expected).
## @param[in] subdir Optional (4th argument) subdirectory relative to
##            `prefix_path` (for example `recursive/cmake`). Empty or
##            omitted keeps the legacy layout under `prefix_path` itself.
## @note On WIN32 uses `CMAKE_IMPORT_LIBRARY_PREFIX`/
##       `CMAKE_IMPORT_LIBRARY_SUFFIX` and '/' separators. On
##       other platforms uses shared library prefix/suffix and '/'. When
##       `prefix_path` is provided it is prepended before the platform
##       prefix. `subdir` is inserted between `prefix_path` and the
##       filename when non-empty.

## @param[in] prefix_path Optional directory prefix to prepend before the

## @param[in] subdir Optional (4th argument) subdirectory relative to
