While installing libinput-1.2 with wacom use flag I the compilation (configuration phase) stopped with the following message: checking for LIBWACOM... no configure: error: Package requirements (libwacom >= 0.12) were not met: Requested 'libwacom >= 0.12' but version of libwacom is 0.11 Enabling libwacom 0.18 with accept keyword fixed the issue.
It was a typo in the dependency specification. Thanks for reporting it.
