Bill, thanks for the info and for the quick reply.
The problem is that I use pkg-config (and stuff like that) to retrieve
my libraries. So CMake does not know wether it is static or shared
libraries to use. Nonetheless I have found a workaround thanks to this
thread: http://www.cmake.org/pipermail/cmake/2006-September/011096.html
So I have just added the following in my CMakeFiles:
    IF (NOT BUILD_SHARED_LIBS)
        SET (LIBRARIES_TO_LINK ${LIBRARIES_TO_LINK} -Wl,-Bstatic
${LIBXSLT_LIBS})
    ELSE (NOT BUILD_SHARED_LIBS)
        SET (LIBRARIES_TO_LINK ${LIBRARIES_TO_LINK} ${LIBXSLT_LIBS})
    ENDIF (NOT BUILD_SHARED_LIBS)
Unfortunately I still have a problem, but which is not due to cmake.
My application indirectly needs to link with -lgcc_s and I do not have
the static library for that, so I get an error :'(
