Anyone who can give a hint why make of project fails? - cmake

Question

when I make the following project: https://github.com/ovrheat/raspberry_rtl_wh1080#readme on my raspberry pi, I end up with errors:
sudo make

How to solve this? I've followed the instructions, but unfortunately no success. The project owner has not replied to a similar question, therefore I try to find an answer here
Is there any lib missing? Any possibility for better debugging?

Answer 1

Solved now. And a big thanks to #fabian. There are two steps:
The includes have been changed (Please follow: Can't compile i2c_smbus_write_byte on Raspberry Pi 4)
The CMakelists.txt in the /src folder needs to be extended on line 38 to the following:
target_link_libraries(rtl_433
${SDR_LIBRARIES}
${CMAKE_THREAD_LIBS_INIT} i2c
)
