When I try to run
I receive this error:
main.cpp:1:18: fatal error: temp.h: No such file or directory #include "temp.h" compilation terminated.
Intellisense however, detects that this header is present.
Ctrl + left-clicking on #include "temp.h" in main.cpp successfully brings me to the file and the line of code has no squiggly lines underneath it.
I have two separate folders for .cpp files and header files and have configured the includePath in c_cpp_properties.json as such: 
My workspace folder is temp and the line "${workspaceFolder}/**" should recursively check subfolders for headers. I added the absolute path to the header files with no success.
