Problem with px4_work_queue

1

Hello! I’m trying to build firmware with my additional modules. I’m expiremeting with fake_gps example. I deleted it from /src/modules and to build firmware as if it is my module. I followed instrustions written here
Module Template for Full Applications.
I created folder mymodules, src in it. “src” contains CMakeLists.txt, and directory “modules”. List of cmakeklists:

set(config_module_list_external
    modules/fake_gps
    PARENT_SCOPE
    )

In modules/fake_gps there is CMakeLists:

px4_add_module(
	MODULE modules__fake_gps
	MAIN fake_gps
	COMPILE_FLAGS
	SRCS
		FakeGps.cpp
		FakeGps.hpp
	DEPENDS
                px4_work_queue
	EXTERNAL
)

I’m building firmware using next command as written in link:

make px4_fmu-v3 EXTERNAL_MODULES_LOCATION=“./…/mymodules”

However, I’m getting next Error list:

CMake Error at /home/work/Firmware_my/cmake/px4_add_module.cmake:235 (get_target_property):
  get_target_property() called with non-existent target "px4_work_queue".
Call Stack (most recent call first):
  /home/work/mymodules/src/modules/fake_gps/CMakeLists.txt:34 (px4_add_module)


CMake Error at /home/work/Firmware_my/cmake/px4_add_module.cmake:236 (if):
  if given arguments:

    "(" "STREQUAL" "STATIC_LIBRARY" ")" "OR" "(" "STREQUAL" "INTERFACE_LIBRARY" ")"

  Unknown arguments specified
Call Stack (most recent call first):
  /home/work/mymodules/src/modules/fake_gps/CMakeLists.txt:34 (px4_add_module)

If I try to build without depending on “px4_work_queue”, it doesnt give such error. Original CMakeLists.txt file in “/src/examples/fake_gps/” contains that line. So it should work I guess…
Can anyone please help me with that trouble?
