That's the issue - lldb-python-doc depends on liblldb. From docs/CMakeLists.txt:
if(EPYDOC_EXECUTABLE)
find_program(DOT_EXECUTABLE dot)
if(DOT_EXECUTABLE)
set(EPYDOC_OPTIONS ${EPYDOC_OPTIONS} --graph all --dotpath
${DOT_EXECUTABLE})
endif()
set(DOC_DIR "${CMAKE_CURRENT_SOURCE_DIR}/doc")
file(MAKE_DIRECTORY "${DOC_DIR}")
#set(ENV{PYTHONPATH}
${CMAKE_CURRENT_BINARY_DIR}/../../../lib/python2.7/site-packages)
add_custom_target(lldb-python-doc
${EPYDOC_EXECUTABLE}
--html
lldb
-o ${CMAKE_CURRENT_BINARY_DIR}/python_reference
--name "LLDB python API"
--url "http://lldb.llvm.org";
${EPYDOC_OPTIONS}
DEPENDS swig_wrapper liblldb
