[CMake] CMake and swig problem

Thanks for your reply Brad,

I did (eventually) spot this line in the SWIG_ADD_MODULE macro.

As I mentioned in conversation with Bill - think the thread accidentally
went private there - I have decided to use my own UseSWIG-Java module
and just remove this line.

This is because I would like to use all the cmake logic in this area
rather than override the PREFIX property with values relevant to all the
platforms I am using (solaris/linux/XP).

Not sure it is the swig convention to generate unix libs with no 'lib'
prefix since it is the target language which controls this platform
specific requirement - java, python etc


Regards
Ian

If you're using SWIG_ADD_MODULE to create the library then the problem
is because that macro creates the library like this:

   ADD_LIBRARY(${SWIG_MODULE_${name}_REAL_NAME}
     MODULE
     ${swig_generated_sources}
     ${swig_other_sources})
   SET_TARGET_PROPERTIES(${SWIG_MODULE_${name}_REAL_NAME}
     PROPERTIES PREFIX "")

The target property is changing the prefix from the default "lib" to "".

  I think this is the convention for loadable SWIG modules.  You can put
your own SET_TARGET_PROPERTIES command after the call to SWIG_ADD_MODULE
to change it back.

Did you do an update with the -d option?
