Currently, several examples do not explicitly state their component dependencies, relying instead on the default behavior that includes all registered components and commonly required ones in the build. Explicitly adding component dependencies can reduce build time when set(COMPONENTS main) is used. Signed-off-by: Frantisek Hrbata <frantisek.hrbata@espressif.com>

Example: General Purpose Timer
This example illustrates how to use gptimer APIs to generate periodic alarm events and how different alarm actions behave on events.
How to Use Example
Hardware Required
- A development board with ESP SOC chip
- A USB cable for Power supply and programming
Build and Flash
Run idf.py -p PORT flash monitor to build, flash and monitor the project.
(To exit the serial monitor, type Ctrl-].)
See the ESP-IDF Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
