[CMake] Shared library versioning (Take 3)

[Fathi Boudra]

hi,

i'll try to add a correct soname to a shared library.

I found some old informations:
http://public.kitware.com/pipermail/cmake/2003-June/003923.html
http://public.kitware.com/pipermail/cmake/2003-June/003985.html

and looked at ITK sources:
#----------------------------------------------------------------------------
- # ITK build configuration options.
OPTION(BUILD_SHARED_LIBS "Build ITK with shared libraries." OFF)
SET(ITK_BUILD_SHARED_LIBS ${BUILD_SHARED_LIBS})

IF(NOT ITK_NO_LIBRARY_VERSION)
  # This setting of SOVERSION assumes that any API change
  # will increment either the minor or major version number of ITK.
  SET(ITK_LIBRARY_PROPERTIES
      VERSION   "${ITK_VERSION_MAJOR}.${ITK_VERSION_MINOR}.
${ITK_VERSION_PATCH}"
      SOVERSION "${ITK_VERSION_MAJOR}.${ITK_VERSION_MINOR}"
     )
ENDIF(NOT ITK_NO_LIBRARY_VERSION)

but i didn't find a proper documentation about it. is there a link somewhere
or other interesting informations that i missed ?

cheers,

Fathi
