# Modules that need to use json manipulation functions will do
# so through the ast_json wrappers which cause the main asterisk
# executable to link to either the system implementation of jansson
# or the bundled jansson.  libjwt also needs to call jansson functions
# directly and if we're not using the bundled version of jansson,
# this works fine bcause the dynamic linker can get the symbols
# directly from the system-installed version of jansson when the
# module using libjwt loads. If we're using bundled jansson however,
# those symbols exist only in the main asterisk executable and a
# library can't resolve against them. The result is that a module
# making jwt_ calls will fail to load at runtime with unresolved
# json_ symbols.  To address this, we create a combined library
# containing both bundled libjwt and bundled jansson so a module
# will have all symbols resolved correctly.
