Cannot add my extension TM1637


Dear all,
I create my extension for TM1637 as above image.
I input source file TM1637Display.h at tab “Add source file” and Upload transcode at tab “Basic configuration”
But when I test and upload code to Arduino Uno R3, it warning error:

C:\Users\John\mblock-avr\temp\build\TM1637\TM1637Display.cpp:24:10: fatal error: TM1637Display.h: No such file or directory #include <TM1637Display.h> ^~~~~~~~~~~~~~~~~ compilation terminated.

Failed to compile file TM1637/TM1637Display.cpp
arduino build failed.

Could you support me to fix the error ?
