I'm currently trying to build the Apache qpid messaging broker on Windows using CMake and the Boost (C++). I went through the initial steps of setting up Qpid on Windows as specified in this file. I set the variable BOOST_ROOT to "C:/< Home >/Downloads/boost_1_61_0" initially so that CMake could find the Boost Libraries (e.g. random, math, chrono, etc.) but I got this log saying that it could only find some of the libraries, but not others. I thought that maybe the filepath needed to include the directory where the Boost libraries were actually located (i.e. C:/< Home >/Downloads/boost_1_61_0/boost) but I was unable to reset the BOOST_ROOT environment variable despite deleting it and creating another one.

I was advised on this forum to delete the cache file for CMake using the GUI so I could reset the variable, but that didn't seem to work either.

Am I using the correct file path for BOOST_ROOT? If not, how should I go about changing it?

    All the libraries you couldn't find have binary components. Do you have Boost .lib / .dll files for your particular toolchain / build generator? – Sam Cristall Jul 06 '16 at 21:06
  • ***to delete the cache file for CMake using the GUI so I could reset the variable, but that didn't seem to work either.*** You could have just reset the value in the GUI. Did you compile boost? Since you are using the most recent boost do you have a recent CMake binary (I am not sure what version will recognize 1.61)? If your CMake does not know about boost-1.61 you can override that with `set(Boost_ADDITIONAL_VERSIONS "1.61" "1.61.0")` before the find_package(boost ...) – drescherjm Jul 06 '16 at 21:19
  • No I didn't compile boost initially, I'm doing the steps in section 5.2.1 [here](http://www.boost.org/doc/libs/1_60_0/more/getting_started/windows.html) for the compilation. For step 3, I'm supposed to run `b2 install` in the directory where Boost.Build should be installed. I'm assuming that this should be boost_1_61_0\tools\build ? – loremIpsum1771 Jul 06 '16 at 21:35

Some of the Boost libraries (e.g. chrono) need to be compiled first. If you have only downloaded Boost library from the website, you probably have not built these libraries. Check Boost website for instructions how to build on Windows. The site also lists which libraries need to be built. Alternatively, you can search for sites where pre-built Boost libraries are hosted. You can download and install from there.
