I'm not sure what you expect SWIG_KERNEL_MODULES to look like, but how
about this:

execute_process(
 COMMAND ${PYTHON_EXECUTABLE} -c "import
sys;sys.stdout.write(';'.join([r'${DOLFIN_SOURCE_DIR}/'+l.split('\"')[1]
for l in open('${CMAKE_CURRENT_SOURCE_DIR}/kernel_modules.i').readlines()
if '%include' in l]))"
 OUTPUT_VARIABLE SWIG_KERNEL_MODULES
)

?

Or perhaps you can use the HEADERS variable defined in
dolfin/CMakeLists.txt instead?
