ARDUINO_SDK_PATH variable is forgotten during compiler check (v0.6.1) #93

Closed lucaspcamargo closed 4 years ago

This also happened using the current master, but I decided to go back to the latest release to ensure that it was not because master was in a WIP state.

I am trying to configure a simple project, but it fails as such:

$ cmake -DARDUINO_SDK_PATH=/home/camargo/sw/arduino-1.8.9 -DCMAKE_TOOLCHAIN_FILE=/home/camargo/git/ghc-fw/Arduino-CMake-NG/cmake/Arduino-Toolchain.cmake ..

!

So, the build system seems to understand where my SDK is (/home/camargo/sw/arduino-1.8.9), but ArduinoSDKSeeker.cmake seems to have not gotten the value. My cmake version is 3.10.2. Any help is appreciated.

@lucaspcamargo As stated here, you should set the ARDUINO_SDK_PATH variable as an environment variable. Passing it as a CMake argument doesn't work, as far as I know.

Oh, sorry. That sailed right over my head. Everything works as expected now.
