VS Code IntelliSense c_cpp_properties.json Include Path not working - c

Question

I am trying to make C IntelliSense functional. Tired of the red squiggly line underneath the statement #include <fftw3.h> in any of my .c files, I added the following configuration to the c_cpp_properties.json file within VS Code:
"includePath": [
"${workspaceFolder}/**",
"~/../../opt/homebrew/Cellar/**"
For reference, I would compile my files with the following command:
gcc test.c -I/opt/homebrew/Cellar/fftw/3.3.10_1/include -L/opt/homebrew/Cellar/fftw/3.3.10_1/lib -lfftw3. My working directory is going to be /Users/jacobivanov/Desktop/College/CFDG. Shouldn't this be working, and if not, why?

Other suggestions:
My C/C++ extension was not requiring a restart or reinstall. Both were tried.
Reset/Restart IntelliSense did not work. Both were tried.
My new error is cannot open source file "fftw3.h"C/C++(1696)
#Patryk Gawroński, unfortunately, I need to use Makefile for other reasons.
