1. Rename PROJECT_NAME in Makefile
2. Update PROJECT_VER in CMakeLists.txt
3. Update project( ##NAME## ) in CMakeLists.txt

To set specific compile time defines (e.g. in case of compiling a project for different architectures esp32, esp32-c3, etc.) do the following:

in the c source files include conditional statements

#ifdef __GPIO_ESP_C3_MINI
   .....
#endif

In project/main/CMakelists.txt add at the bottom:

add_compile_definitions( __GPIO_ESP_C3_MINI=1)
