Function returning git revision

[pdziekan]

Currently, git revision of libcloudphxx is stored in a header file.
Software that dynamically loads libcloudphxx (e.g. UWLCM) needs to be recompiled after new version of libcloudph++ is installed in order to output proper git revision of libcloudph++.

This could be improved if libcloudph++ defined a function returning the git revision.

I concur this would be useful, but rather to implement a "you are dynamically linking with different version of libcloudph++ than UWLCM was compiled against" warning (or error).

The point is that when compiling UWLCM with libcloudph++ headers, some constants or even more elaborate logic gets compiled into the UWLCM binaries (e.g., p_vs(T) function). Now, imagine libcloudph++ gets a new implementation of p_vs(T) - then the case definition would be inconsistent with what is happening while time-stepping.
