this carries through into the Targets.cmake file we install which in
turn means that the imported target for the consumer defines its include
directory. this removes the need to manually add the include dir
also updated the readme accordingly
According to the smartctl man page:
```
EXIT STATUS
The exit statuses of smartctl are defined by a bitmask. If all is well with the disk, the exit status (return value) of smartctl is 0 (all bits turned off). If a problem occurs, or an error, potential error, or fault is detected, then a non-zero status is
returned. In this case, the eight different bits in the exit status have the following meanings for ATA disks; some of these values may also be returned for SCSI disks.
Bit 0: Command line did not parse.
Bit 1: Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode (see '-n' option above).
Bit 2: Some SMART or other ATA command to the disk failed, or there was a checksum error in a SMART data structure (see '-b' option above).
Bit 3: SMART status check returned "DISK FAILING".
Bit 4: We found prefail Attributes <= threshold.
Bit 5: SMART status check returned "DISK OK" but we found that some (usage or prefail) Attributes have been <= threshold at some time in the past.
Bit 6: The device error log contains records of errors.
Bit 7: The device self-test log contains records of errors. [ATA only] Failed self-tests outdated by a newer successful extended self-test are ignored.
```
BUG: 429028
Empty labels are not allowed anymore.
One can reset them with -r flag but that is not supported in older
dosfstools. So for now we just manually set label to NO_LABEL.
BUG: 432941
As the sfdisk man page says on the option '--wipe' that
specifies whether or not to wipe signatures in order
to avoid collisions:
> When this option is not given, the default is auto,
> in which case signatures are wiped only when in interactive mode
but sfdisk is not run in interactive mode here, since
stdin does not refer to a terminal, and the sfdisk
man page says:
> It [i.e. sfdisk] runs in interactive mode if executed on terminal
> (stdin refers to a terminal).
Therefore, explicitly pass the '--wipe=always' option to
sfdisk so that old signatures are wiped when a new partition
table is created.
Bug: 431628
Move include of BLKID_INCLUDE_DIRS into scope it is used.
UUID_INCLUDE_DIRS is unused, left over from before partitionmanager
switched away from libuuid in 26e7f9d7ef306d61380e1c8965feb83bb6b07d18 .
Explicit Qt5Core_INCLUDE_DIRS no longer needed.
src/ is automatically available for kpmcore target, also exposed in
its build link interface.
