title: macOS x: boost .hpp not found compiling qt5 project with make
body: <p>I am trying to build an example qt5 project where Makefile is built with qmake.  clang++ gives me this error:</p>
  
  <p>fatal error: 'boost/numeric/ublas/vector.hpp' file not found</p>
  
  <p>Since Makefile is generated by qmake, it is difficult edit the huge Makefile -I include paths to find boost header files ( which is in /usr/local/include/boost ).</p>
  
  <p>Is there a way to specify additional include paths in qmake that would help?</p>
