1d14d6ee-fd63-4fa1-bfa4-8f47b42119f0 - appears to be a Silicon Labs (formerly BlueGiga) OTA Service for updating firmware, which would make sense.

Additionally, the Pokit Meter includes the following undocumented service:

Additionally, the Pokit Pro includes the following undocumented services (added somewhere between firmware v1.8.1 and v2.0.2):

Also, the Pokit app contains references to the following UUIDs; these may or may not be BLE services.

QtPokit requires Qt's support Bluetooth Low Energy, in Central mode.

In summary (of the below table), for building QtPokit:

CMake 2.8.9 through to pre-3.0 should be possible, but the effort and resulting complexity is high enough to not be worth it.
any CMake 3.x should be fine, except:
CMake 3.12+ is needed for the full set of unit tests.

Version	Dependency
2.8.9	Qt 5.1+
2.8.11	`target_include_directories`
2.8.11	Has `-fPIC` issues with Qt.
2.8.12	`add_compile_options`
2.8.12	Has compile isssues with Qt.
3.0	`VERSION` option of the `project()` command.
3.1	Qt 5.11+
	`target_sources` command.
3.12	Object Libraries for sharing binary objects between the console app and unit tests.
3.13	`-B` CLI option (handy, but not essential).
3.16	Qt6.x shared
