gcc/g++ cant find include files

[ghost]

Title sums it up, I have a cpp project with a src and include directory using, I have seen some similar issues, (#589, #603, #1024)

let g:neomake_cpp_enabled_makers = ['gcc']
let g:neomake_cpp_clang_maker = {
\ 'exe': 'g++',
\ 'args': ['-Wall', '-Iinclude', '-Wextra', '-Weverything', '-pedantic', '-Wno-sign-conversion'],
\ }

doesnt work but using clang instead works.

let g:neomake_cpp_enabled_makers = ['clang']
let g:neomake_cpp_clang_maker = {
\ 'exe': 'clang++',
\ 'args': ['-Wall', '-Iinclude', '-Wextra', '-Weverything', '-pedantic', '-Wno-sign-conversion'],
\ }

By the way, I'm operating in the parent directory to both of these files.
The error neomake outputs on the header file in the following would be: "gcc fatal error music.h no such file or directory"

stuff
#include "music.h"

Expected behavior

I expected g++ to find the header file with -Iinclude

Output of the ":verb NeomakeInfo" command

You are only configuring clang in the first case also (let g:neomake_cpp_clang_maker).

using 'let g:neomake_cpp_gcc_maker' solved the problem
