dnl for the linker to understand which versions the library are compatible with
dnl each other we must keep a separate library version cout of the format c:r:a.
dnl - if only implementation changed but all interfaces are kept, do r++
dnl - if only functionality was added do c++,r=0,a++
dnl - if any functionality was removed do c++,r=0,a=0.
