Background history:

2 weeks ago, I have received ESP32-DevKitC from Digikey.
And I have tested DevKitC successfully after installing esp-idf(ver 4.0), idf-eclipse-plugin.
Recently I have received ESP32-Sense Kit, so I think to test the touch sensor.
But the documents suddenly says to use make ...

Following output shows the problem.


C:\Users\daekyu\esp\esp-iot-solution\examples\touch_pad_evb>%userprofile%/esp/esp-idf/export
Setting IDF_PATH: C:\Users\daekyu\esp\esp-idf

Adding ESP-IDF tools to PATH...
No directories added to PATH:

C:\Users\daekyu\.espressif\tools\xtensa-esp32-elf\esp ...

I am new to esp.
I have install esp-idf and idf-eclipse-plugin, those function well.
But when I install esp-iot-solution, that confused me so much.
I cannot build the example "touch_pad_evb".
Please help me!
