Ale: Add all headers for clang and gcc linters

[Njiallu]

Hi, so i'm a bit new with ale so i want to know what i should do to correctly include my headers with c and cpp using clang and gcc.
I know about issues #324 and #208 but i dont know how to use their information.
I want it to search recursively from the vim path but my usual working tree is:

• ./
• includes/
  > - subdirs/
• srcs/
  > - subdirs/
  ...

and in my rc i use

let g:ale_cpp_clang_options = "-std=c++14 -Wall -I../** $(sdl2-config --libs) "

What went wrong

I want clang to be able to avoid this error:

If you have a Makefile for your project, try setting g:ale_c_parse_makefile to 1. Some support has been added recently for parsing the output of make -n to figure out where headers are. It might not work perfectly yet. Beyond that, try setting b:ale_c_gcc_options or b:ale_c_clang_options (Or g: for global variable versions) to include all of the headers you need. See :help ale-c for all of the options for C linters.

Is there a way for me to tell my compiler via ale to look recursively for headers from the vim path or something else?

[w0rp]

There's no way to tell your compiler to do that. Have you tried the make -n parsing option I recommended trying above?

[Njiallu]

It seems to work but including something like the SDL is not working out tho. I tried adding `sdl2-config --cflags` to g:ale_cpp_clang_options

The GitHub issue template now recommends asking for help with configuring ALE on Stack Exchange or Reddit instead.
