Can't resolve namespace memeber

Hi all,

I'm trying to use CLion for a project where we use tinyformat.

http://github.com/c42f/tinyformat 

If I clone and open the project it looks ok, but any use of the functions defined in tinyformat.h using the namespace "tfm" won't work.

Something like

#import "tinyformat.h"

void test(){
    tfm::printf("My value is '%s'\n", "a test");
}

in a test.cpp file would highlight "can't resolve namespace member printf".

I'd love if somebody could help me better debug the issue.
