ninja: error: rebuilding 'build.ninja': subcommand failed

I get the following error when I try to flash the program into the microcontroller. The compilation is done without problems. Does anyone know what I'm doing wrong?

CMake Error at C:/esp-idf/tools/cmake/component.cmake:302 (message): Include directory 'D:/Eclipse/Trabajo/ESP32_oled_i2c_u8g2/main/csrc' is not a directory.

Thanks in advance

Modify some things and now the error I get is the following:
