Add missing json-c dependency
json-c is an explicit dependency when building it with the
ENABLE_KEYBOARD
option (default on).
The dependency in fcitx5 is listed in https://github.com/fcitx/fcitx5/blob/1fa2b924e0465209e69f736152db2edf9d4ad5f7/CMakeLists.txt#L160.
Probably this missing dependency was undetected because json-c
is required by cryptsetup
, which is included in base
.
