I am trying to use an open source SDK in VS Code and for some reason I can’t compile. Hopefully this will be very easy to answer.

I always get this error: test.c:22:10: fatal error: linphone/core.h: No such file or directory 22 | #include "linphone/core.h"
My code is extremely simple:

#include "linphone/core.h"
#include <signal.h>

• I am using VS Code through SSH on a remote Ubuntu machine.

• Most libraries depend on other libraries in the FOSS project, so I would really want to add the whole folder and it’s sub-folders as dependency.

• The project tree looks like this:
  MyProject
  |_ linphone-sdk
  | |_ include
  | |_ linphone
  | | |_ core.h
  | |_ mediastreamer2
  | | |_ bitratecontrol.h
  | |_ a bunch of other folders
  |_ helloworld.c

• I tried compiling with gcc manually and it didn’t work. gcc test.c -o test -I/linphone-sdk/include/linphone/core.h or even gcc test.c -o test -I/home/user/Documents/MyProject/linphone-sdk/include/linphone/core.h

• I modified tasks.json in a similar way as manually calling gcc

• The only way I can get the library to “work” is by doing #include "linphone-sdk/include/linphone/core.h" instead of "linphone/core.h" but then I get errors like path/to/my/project/linphone-sdk/include/linphone/core.h:24:10: fatal error: mediastreamer2/bitratecontrol.h: No such file or directory which is what I would expect (see project tree).

There is probably a better way to get it to work than changing every include one by one until it works, right?
