Buzz click on hexiwear

[iometrine]

Hello,

I'm sorry, i don't know if i'm in the good place to ask this, but i try.
I have two projects kds on separate workspace.
The first is hexiwear, it builds and it works and the program run on the watch
The second is buzz click it builds and it works as well and the program run on the watch, i can heard the melody with the buzz on the slot3

I should like to add the buzz function in the hexiwear program.
So i begin to merge just the main.h and i try to load the list a lib.

My problem is, when i load one of them ,
#include "fsl_enet_driver.h"
#include "fsl_ewm_driver.h"
#include "fsl_flexbus_driver.h"
#include "fsl_vref_driver.h"
#include "fsl_wdog_driver.h"

My project doesn't build and i got an error
arm-none-eabi-g++: error: CreateProcess: No such file or directory
makefile:143: recipe for target 'HEXIWEAR_MK64.elf' failed
make: *** [HEXIWEAR_MK64.elf] Error 1

Have you an idea, or maybe there is another way to do that.

Thanks for your help.
