Add version numbers to commandline tools

[dominicgs]

It would be nice to have version numbers added to the tools in the same way that we add them to the firmware. Running ubertooth-rx -v would give the output for Ubertooth and probably libbtbb, e.g. Ubertooth 2014-02-R2, libbtbb 2014-02-R2 or Ubertooth git-ae7923f, libbtbb git-83b7ca6.

This is going to take some doing under cmake. Possible solution:

I was thinking that we'd use the same method as we do for pkg-config files: https://github.com/dominicgs/USBProxy/blob/master/src/lib/usbproxy.pc.in https://github.com/dominicgs/USBProxy/blob/master/src/lib/CMakeLists.txt

Added some initial support in commit 00b38e6. A couple of questions: Should we version the tools separately from the lib? Should we also version libbtbb and print it at the same time? The formatting looks a bit strange, better ideas are welcome.

00b38e6 breaks the build for me:

CMakeFiles/ubertooth-btle.dir/ubertooth-btle.c.o: In function `main':
ubertooth-btle.c:(.text+0x48a): undefined reference to `h_pcap_le'
ubertooth-btle.c:(.text+0x49b): undefined reference to `h_pcap_le'
ubertooth-btle.c:(.text+0x4e5): undefined reference to `h_pcap_le'
ubertooth-btle.c:(.text+0x4f6): undefined reference to `h_pcap_le'
collect2: error: ld returned 1 exit status

[dominicgs]

Yes, known issue, already fixed on master.

Where did MAJOR and MINOR come from? If we include those, they should be in sync with YYYY.MMRN format.

I think it would be wise to add the same functionality to libbtbb. A simple char *btbb_version(void) that we can call from Ubertooth utilities would be sufficient.

[dominicgs]

MAJOR and MINOR come from the library version number, they're set in a higher level CMakeLists.txt file. They aren't in sync with the release number because we don't always bump the library version with a release.

[mikeryan]

My ideal format: ubertooth git-00f80d5*, libbtbb git-1234567, libUbertooth 0.2 For releases it would look like: ubertooth 2014-11-R1, libbtbb 2014-11-R1, libUbertooth 0.2

Be sure to update the release procedure wiki page so that the releases have symbolic names instead of git commits.

Done - in a number of commits because it's sort of required for testing.
