Summary0032856: Configuration, CMake - SONAME should include minor version in addition to major to reflect ABI compatibility
DescriptionThe OCCT ABI has changed with every minor version in the past, but the version in the SONAME has been kept.

readelf -a /usr/lib64/libTKCAF.so.7 | grep SONAME
 0x000000000000000e (SONAME) Library soname: [libTKCAF.so.7]

This makes it very hard to keep the dependencies correct in dependent software.

The correct SONAME for libTKCAF would be `libTKCAF.so.7.6`, assuming the ABI is kept between 7.6.0 and 7.6.1
Steps To ReproduceUpdate OCCT from 7.5.3 to 7.6.1

Try to start e.g. FreeCAD, which will abort with a runtime linker error due to missing symbols.

"/usr/lib64/FreeCAD/lib/Part.so: undefined symbol: _ZN24BRepBuilderAPI_MakeShape5BuildEv"
Additional information
and documentation updates		Most Linux distributions (e.g. RHEL/Fedora, SLE/openSUSE, Debian) package libraries in a way which makes different versions co-installable. This allows to keep an older version when not all dependent packages are compatible with newer versions (e.g. FreeCAD last stable release 0.19.3 is only compatible with OCCT 7.5.x).

For this to work, the SONAME has to be updated on ABI change, otherwise a newer version is considered a compatible replacement for the old version.

 @StefanBruens, I guess that `SOVERSION` in `adm/cmake/occt_toolkit.cmake`:
if (ANDROID)
  # do not append version to the filename
  set_target_properties (${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "${PRECOMPILED_DEFS}")
else()
  set_target_properties (${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "${PRECOMPILED_DEFS}"
                                                    SOVERSION     "${OCC_VERSION_MAJOR}"
                                                    VERSION       "${OCC_VERSION_MAJOR}.${OCC_VERSION_MINOR}.${OCC_VERSION_MAINTENANCE}")
endif()

should be changed from "${OCC_VERSION_MAJOR}" to "${OCC_VERSION_MAJOR}.${OCC_VERSION_MINOR}" to include minor release version.
Minor version bumps never preserve ABI, so it doesn't make sense relying only on major version in SONAME.

Technically, maintenance version bumps in OCCT might break ABI too, when patches are backported without caution.
But if we speak about Linux distros, I think that maintaining several micro versions (like 7.6.0 and 7.6.1) as dedicated packages wouldn't make much sense.

On a cursory glance, using `SOVERSION "${OCC_VERSION_MAJOR}.${OCC_VERSION_MINOR}"` has the wanted effect (using TKCAF as example, same for all other libs):

- SONAME in the ELF dynamic section becomes libTKCAF.so.7.6
- CMake adds libTKCAF.so and libTKCAF.so.7.6 symlinks to libTKCAF.so.7.6.1, no libTKCAF.so.7

Kirill,

1. There is a small misprint in the commit message "SOVERSIOn length" (SOVERSIOn - both OCCT and Products are affected).
2. Naming convention in CMake. I've seen that you're using the OCCT's naming style (`aSoVersion`). We historically employ UPPER_CASE naming in CMake. Does it sound good for you to keep original naming?
