SDK not found on Debian 9 with official Arduino binary

[joede]

I've tried to build your example "hello-world". My system is a Debian 9 with the official binary tarball installed in /home/jd/local/arduino-1.8.9. To test your project, I have clones it into /home/jd/tmp. So I select the directory of the example and passed the full path to Arduino-Toolchain.cmake and the full path to the root of the Arduino SDK path. This is the result:

$ cd Arduino-CMake-NG/examples/hello-world
$ mkdir .build && cd .build
$ cmake -DCMAKE_TOOLCHAIN_FILE=../../../cmake/Arduino-Toolchain.cmake -DARDUINO_SDK_PATH=/home/jd/local/arduino-1.8.9 ..

@joede Hi, please try to set ARDUINO_SDK_PATH as an env variable.

Sotry for the delay... I have set ARDUINO_SDK_PATH in my ~/.profile and removed it from the parameters list of my CMake call. And it works! Thank you!
