title: dbus/dbus.h no such file or directory when building to arm
body: <p>I'm trying to cross compile my project to arm to use it on a raspberry pi but it can't find dbus. Which was easily find when I was compiling classically.
  I'm using cmake I've added dbus-1 to target link library and I'm using arm-linux-gnueabihf to cross compile.</p>
  
  <p>Any idea?</p>
  
  <p>EDIT: add my CMakeLists.txt :</p>
