[CMake] CMake and soversions in Linux

[Pau Garcia i Quiles]

Hello,

I am trying to set soversion and information in a library in Linux  
using CMake 2.4.7.

Assuming version = 2.0.6 and soversion = 0.0.0 (because it's going to  
be the first soversioned release and we are not going to check the  
history of the library and see where ABI compatibility was broken and  
in what way), if I use:

   SET_TARGET_PROPERTIES(
     wt
   PROPERTIES
     VERSION 2.0.6
     SOVERSION 0.0.0
   )

I get this:
lrwxrwxrwx 1 root root      14 2007-09-24 09:56 /usr/lib/libwt.so ->  
libwt.so.0.0.0
  lrwxrwxrwx 1 root root      14 2007-09-24 09:56  
/usr/lib/libwt.so.0.0.0 -> libwt.so.2.0.6
  -rw-r--r-- 1 root root 1935368 2007-09-22 13:02 /usr/lib/libwt.so.2.0.6

Which is fine according to the libtool manual  
(http://www.gnu.org/software/libtool/manual.html#Versioning) but it's  
not the best way to provide versioning and soversioning information.  
I'd like to follow section 6.4 in the libtool manual  
(http://www.gnu.org/software/libtool/manual.html#Release-numbers),  
thus getting this:

lrwxrwxrwx 1 root root      14 2007-09-24 09:56 /usr/lib/libwt.so ->  
libwt-2.0.6.so.0.0.0
  lrwxrwxrwx 1 root root      14 2007-09-24 09:56  
/usr/lib/libwt-2.0.6.so.0 -> libwt-2.0.6.so.0.0.0
  -rw-r--r-- 1 root root 1935368 2007-09-22 13:02 /usr/lib/libwt-2.0.6.so.0.0.0

I tried using OUTPUT_NAME in SET_TARGET_PROPERTIES:

   SET_TARGET_PROPERTIES(
     wt
   PROPERTIES
     VERSION 2.0.6
     SOVERSION 0.0.0
     OUTPUT_NAME wt-2.0.6
   )

but the output is not what I expected:

lrwxrwxrwx 1 root root      20 2007-09-25 12:38  
/usr/lib/libwt-2.0.6.so -> libwt-2.0.6.so.0.0.0
lrwxrwxrwx 1 root root      20 2007-09-25 12:38  
/usr/lib/libwt-2.0.6.so.0.0.0 -> libwt-2.0.6.so.2.0.6
-rw-r--r-- 1 root root 1933696 2007-09-25 12:15 /usr/lib/libwt-2.0.6.so.2.0.6

How do I do to obtain filenames compliant with section 6.4 of the  
libtool manual?

Thank you.
