Hi,
I am using Arduino Ide 1.8.7, I installed the library SparkFunMPU9250-DMP.h and I used it in my project and everything was successfully compiled. 
But if I open the same project in the Visual Studio community  2017 (with the visual micro plugin installed obviously) can not compile the project.

the output says

     An error was encountered during the 'Deep Search' library discovery process.
Build failed for project 'MainProgram'

I tried to add a new path in VC++ Directories > reference directories but can not compile. 

do you have any advice? 

thanks !!!
