[fluid-dev] compatibility version problem

[Ebrahim Mayat]

Hello again

In the transition from autotools to cmake on OS X, I came across  
version number compatibility issue for the libfluidsynth shared  
library..

The names and version numbers of libfluidsynth are:

1. using autotools for the previous version of fluidsynth-1.1.1

/sw/lib/libfluidsynth.1.dylib (compatibility version 5.0.0, current  
version 5.0.0)

2. autotools with fluidsynth-1.1.2 gives

/sw/lib/libfluidsynth.1.dylib (compatibility version 6.0.0, current   
version 6.0.0)

3. while building with cmake for fluidsynth-1.1.2 gives

/sw/lib/libfluidsynth.1.dylib (compatibility version 1.0.0, current  
version 1.4.0)

The problem arises due to the fact that updating from 1.1.1 to 1.1.2,  
there is a concomitant downgrade of compatibility version from 5.0.0  
to 1.0.0.
This downgrade can break all programs that link to the previous  
version of libfluidsynth resulting in distribution breakage.

Two possible solutions could be:

1. Revert to autotools so that the compatibility version also upgrades  
(from 5.0.0 to 6.0.0).

2. Force cmake to increase the compatibility version. (I don't know  
how I would do this but there is probably a way ? )
