Can't build HPX with CMake on Windows - found [Boost] suitable version “1.75.0”, minimum required is “1.61”

Question

I'm trying to build HPX with CMake on Windows 10 (the end game is to build OpenCV with MSVC).
I have downloaded Boost 1.75.0, ran bootstrap.bat then b2.exe from an admin CMD. I then added the path to the boost folder to PATH variable. Next I opened CMake and tried to build HPX 1.3.0 and got the following error:

  New Boost version may have incorrect or missing dependencies and imported

Please help!

Looks like CMake found the Boost header files but not the Boost binaries. I would try explicitly setting the BOOST_INCLUDEDIR and BOOST_LIBRARYDIR CMake variables pointing to the corresponding directories. See also https://cmake.org/cmake/help/latest/module/FindBoost.html for more CMake variables you could set.

Note also, that the warnings issued in your logs are benign and caused by your CMake version being older than Boost V1.75.
