title: Build Boost vs. include the headers
body: <blockquote>
    <p>Nothing to Build?</p>
    
    <p>Most Boost libraries are header-only: they consist entirely of header
    files containing templates and inline functions, and require no
    separately-compiled library binaries or special treatment when
    linking.</p>
  </blockquote>
  
  <p>I saw many people asking how to build Boost for Microsoft Visual C++, MinGW, and GCC...But Boost says they provide header-only libraries. Why not simply include these headers in the project, like using static libraries. Does the pre-building of Boost work only for saving the compilation time of the project? </p>
