vscode cannot find header when compile while Intellisense can

Question

Question Updated: I\'m trying to build a c++ project on vscode using the C/C++ extension. The compiler complains about not finding header files (actually boost

c_cpp properties is for intellisense. It is not used for compiling. The compiler is there only because it is queried to find the default include paths it uses for system headers.

The tasks defines how the build task runs.

Vscode doesn't connect the two.
