CMake script for add eternal libaray ( BSEC ) to test Bosch sensor raeding?

[Mohit Nama]

hello,

i have downloaded    ( BSEC )    library from https://www.bosch-sensortec.com/software-tools/software/bsec/  for read sensor data . now want to test the code by build and flashing it with VS code for thingy 91 borad.

CMamke  file have 

FILE(GLOB bsec_integration src/*.c)

target_sources(app PRIVATE src/bsec_integration.c)
target_sources(app PRIVATE src/bme680.c)

i have add c file and header file in scr folder .

on build shows error 

FATAL ERROR: command exited with status 1: 'c:\Users\mohit\ncs\v1.9.1\toolchain\opt\bin\cmake.EXE' '-DWEST_PYTHON=c:\Users\mohit\ncs\v1.9.1\toolchain\opt\bin\python.exe' '-Be:\Nordic_Acadmey\bsec_integration\build_1' '-Se:\Nordic_Acadmey\bsec_integration' -GNinja -DBOARD=thingy91_nrf9160 -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=On -DNCS_TOOLCHAIN_VERSION:STRING=NONE.

please suggest
