Clion Arduino plugin: Error:Could not find Arduino SDK (set ARDUINO_SDK_PATH)

Question

I am trying to setup CLion as my workspace for my arduino. I have installed the two Arduino plugins for CLion, generated a new sketch project, but I am getting cmake errors on opening the project.

CMake Error at /cygdrive/c/Users/user/project/cmake/ArduinoToolchain.cmake:86 (message):
 Could not find Arduino SDK (set ARDUINO_SDK_PATH)!
Call Stack (most recent call first):
 /cygdrive/c/Users/user/project/CMakeFiles/3.9.4/CMakeSystem.cmake:6 (include)
 /cygdrive/c/Users/user/project/CMakeFiles/CMakeTmp/CMakeLists.txt:3 (project)

The issue is similar to this logged issue here: https://github.com/francoiscampbell/CLionArduinoPlugin/issues/11

As a Windows 10 user, I have the Arduino SDK installed here: C:\Program Files (x86)\Arduino

What's interesting is that the cmake file is calling the UNIX commands when it's running in this if statement:

 if(UNIX)
 file(GLOB SDK_PATH_HINTS /usr/share/arduino*
 /opt/local/arduino*
 /opt/arduino*
 /usr/local/share/arduino*
 )
 elseif(WIN32)
 set(SDK_PATH_HINTS "C:\\Program Files\\Arduino"
 "C:\\Program Files (x86)\\Arduino\\libraries"
 )
 endif()

• Stephane Zundel: I have the same error, even if I set it manually: set(ARDUINO_SDK_PATH C:\\Program Files\\Arduino) I checked my path, but nothing wrong in the arduino path, I'm using Cygwin if it can help...
• Thom: Me too. Did you ever figure this out?
• John Snow: unfortunately no :(
