As for the /include -- boost libraries have the structure of libs/<libname>/include/boost/<libname> when they are in github repos. When a release is made all those libname directories moved into BOOST_ROOT/boost. So there's no 'include directories' in the distro after that. AFACT date_time and program_options are the same on that. > A quick peak at > /lib/cmake/boost_program_options-1.72.0/boost_program_options-config.cmake > That file and path isn't in my 1.72 release.... > compared to the same file from date_time didn't give me any obvious hint > though.

Also, you should know that boost system can be used header only -- as can date_time (just avoid old legacy i/o features). Here's the error message from my program's cmake: > [...] > Imported target "Boost::program_options" includes non-existent path > "/include" > in its INTERFACE_INCLUDE_DIRECTORIES.
