Converting .cpp file to .wasm file

Question

I have a .cpp file that imports the microsoft seal library

#include "seal/seal.h"

it imports without any errors but when i try to convert the file to .wasm, i get an error saying

fatal error: 'seal/seal.h' file not found
#include "seal/seal.h"
         ^~~~~~~~~~~~~~~~
1 error generated.

I'm stuck. Does Anyone have any ideas ?
