Comment:

 This is bug in upstream's CMake project. I've provided the details in the
 issue you submitted (https://github.com/kpeeters/cadabra2/issues/331), and
 copied here for completeness:

 Per the output from `cmake --help-module FindBoost`, the problem appears
 to be twofold:

 {{{
 FindBoost
 ---------

   This module is available only if policy ``CMP0167`` is not set to
   ``NEW``.  Port projects to upstream Boost's ``BoostConfig.cmake``
 package
   configuration file, for which ``find_package(Boost)`` now searches.
 }}}

 In short:
 * The project is setting `CMP0167` to `NEW`, which prevents use of
 `FindBoost`
 * The project is still referencing `FindBoost`, when it needs to be
 changed to `BoostConfig`
