[Swig-user] How to add CMAKE SWIG module with no interface

[Mariusz G. <ali...@gm...>]

Hello,
I'm having problems in adding SWIG wrapper generation to cmake project without 
.i (interface) files.
I thought i had it already working but today i changed something and can't get 
make it work once again.

Currently CMakeLists.txt looks like that:
<code>
FIND_PACKAGE(SWIG REQUIRED)
INCLUDE(${SWIG_USE_FILE})

SET_SOURCE_FILES_PROPERTIES(file.h PROPERTIES CPLUSPLUS ON)
SET_SOURCE_FILES_PROPERTIES(file.h PROPERTIES SWIG_FLAGS "-d2 -includeall")
SET(CMAKE_SWIG_OUTDIR ${CMAKE_CURRENT_BINARY_DIR})
SWIG_ADD_MODULE(example D file.h)
SWIG_LINK_LIBRARIES(example ${D2_LIBRARIES})
SET_TARGET_PROPERTIES(example PROPERTIES LINKER_LANGUAGE C)
</code>
which results in generated libexample.so, but no .d (wrapper side source) files 
exists. I'm new in cmake and swig, so i bet it's some kind of stupid mistake, 
but i'm struggling with it too much and simply out of ideas since grepping on 
CMake folder gives me no /usr/bin/swig anymore. Why it doesn't generate swig 
binary call, and how is libexample.so generated then - those questions are 
still opened for me.

Thanks for hints,
