[CMake] CMake and swig problem

[Judicaël Bedouet]

Hello,

I have a problem with Swig libraries generated by CMake and I find a
mail from 2006 which describes the same problem.

To summarize, SWIG libraries for Java must be generated with a lib
prefix under Linux and CMake generates without prefix because some
languages like Python don't need a lib prefix.

In 2008, with JDK 1.6 (1.6.0_06) and CMake 2.6.0, we always have to
preprend 'lib' for Unix platforms.

Is there no way that CMake preprend automatically lib for Java modules
on Unix platforms, in fact keep default naming convention ?

Thanks,

J. Bedouet

P.S. For the moment, I do this after swig_add_module and swig_link_libraries.
set_target_properties (myjavalib PROPERTIES PREFIX lib)
