CMakeLists.txt problem with the file

Question

I have project, the main,c in the src folder, in the src folder - I open folder in the name sensor and in this folder i have the sensor.c file, and the sensor.h file. when I try to build and flash - it's build and flash, but i didn't see any message... 
 when I took the sensor.c code, and put in the main.c - it's working like a magic!! what the problem with my CMakeLists.txt files? in the sensor folder, in the CMakeLists.txt file: target_include_directories(app PRIVATE .) target_sources(app PRIVATE sensor.c sensor .h) 
 
 in the CMakeLists.txt (in the project): 
 # SPDX-License-Identifier: Apache-2.0 
 cmake_minimum_required(VERSION 3.20.0) 
 find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE}) project(hello_world) add_subdirectory(src/sensor) target_sources(app PRIVATE ${app_sources})

Hello, 
 Are you getting any error message when building the application? If your CMAKE configuration is not proper then you won't be able to build the application. Take a look at this sample where my colleague added BLE support by defining another header file. Check the CMAKE file of same project. 
 
 Kind Regards,

Thank you so much for your help, there is probably some problem with the code and I guess I can get along with it. 
 In any case, I will upload the structure of the CMAKE I defined and it does run for those who need to be needed later. in the CMakeLists.txt file (in the main folder): 
 # SPDX-License-Identifier: Apache-2.0 
 cmake_minimum_required(VERSION 3.20.0) 
 find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE}) project(hello_world) add_subdirectory(src/sensor_folder) target_sources(app PRIVATE ${app_sources}) CMakeLists.txt file in the sensor folder: (src\sensor_folder) target_include_directories(app PRIVATE .) target_sources(app PRIVATE sensor.c sensor .h)
