Not able to find user_config.jam while installing boost libraries
I'm trying to compile a Kinect v2 point cloud example created by someone else, on windows 8.1. This Visual studio example has a dependency on a library called
libboost_mpi-vc120-mt-gd-1_57.lib
I googled for a long time but did not find a downloadable version of this pre-compiled library (there are downloadable versions of pre-compiled boost libraries, but they don't contain binaries for the boost MPI library), so I decided to build one. Every time I try to build boost library it says
"warning: skipping optional Message Passing Interface (MPI) library.
note: to enable MPI support, add "using mpi ;" to user-config.jam."
Every forum as well as the boost documentation I checked says that user-config.jam needs to be modified and adding 'using mpi;' to it compiles the libs for mpi.
However I'm not able to find a file called user-config.jam anywhere the boost folder (except one site-config.jam and one user-config.jam in pathto\boost_1_57_0\tools\build\example\).
All forums say there should be a user-config.jam in pathto\boost_1_57_0\tools\build\ but I did not find any. So I created my own user-config.jam in that location and added 'using mpi;' to that file but it still doesn't compile the mpi libs. I also tried putting one user-config.jam in pathto\boost_1_57_0 and installing again from the pathto\boost_1_57_0 but I get the same result (i.e. no MPI binaries anywhere).
The way I'm building is as mentioned on the official documentation here. Even though the documentation says boost cannot build without user-config.jam, I was actually able to build it from the pathto\boost_1_57_0 folder; so I'm stumped as to what's going on.
Is there anything I'm missing. All this is just because the VStudio project has a dependency on that one lib file. And the one lib file I need belongs to the one library boost isn't building :(. If anyone has it (libboost_mpi-vc120-mt-gd-1_57.lib) and can attach it that'll be great as well :). Thanks in advance

However I'm not able to find a file called user-config.jam anywhere the boost folder (except one site-config.jam and one user-config.jam in pathto\boost_1_57_0\tools\build\example).
The directory you're looking for is pathto\boost_1_57_0\tools\build\src.
In other words, create and edit the following file:
pathto\boost_1_57_0\tools\build\src\user-config.jam.
You can start off from the example file if you want pathto\boost_1_57_0\tools\build\example\user-config.jam, by copying it to the aforementioned location.
