Use hand-inserted version. Remove one Git pass.pr_62

Full version name should consist of official version and Git one
Git describe should never fail with --always switch
Add more build specific information
Save compilation definitions and flags
Move getting information to the end of CMakeLists.txt
Use configuration over definitions
Proper implementation in C API for getting version
Test case for getting version.
Working configure file
