using compile_commands.json cannot find system includes

[dirvine]

i.e. no etc.
This issue requires that as far as I can tell you
1: create the json fiel and then with vim do something like

:%s/-w /-I\.usr\/include\/c++\/v1 -w /g 

2: Have cmake do this by explicitly stating the dir in CmakeLists.txt (which is not recommended)

Is it possible to
a: Have ycm use installed clang
b: Allow additional flags to be passed when using json [this may prove useful for other reasons i.e. unsetting flags if necessary with -fno- etc.]
c: Fix the bug :-)

Thanks for the so far excellent tool though, it's very cool.

I hope this makes sense.

I think this is a duplicate of #303.

The underlying problem is that compiling something through libclang does not use the default system include paths, but compiling it through clang does. Maddening, isn't it?

Just fyi I resorted to creating my own flags and adding to the flags section, it seems that the json approach for now will cause problems that cannot be overcome (.h files etc). Yea it is maddening, but I suppose it's how it is, even so fantastic lib chap, great job indeed. I agree with the dup/close as well, sorry I never looked more closely.
