The problem is due (or we could say triggered) to multiple cmake options for boost.
In soma-io, it is used the default way:

find_package( Boost REQUIRED )

Then in highres-cortex, it is used differently:

# Do not use BoostConfig.cmake from boost-cmake, because its behaviour may be
# different from regular FindBoost.cmake.
set(Boost_NO_BOOST_CMAKE ON)
# All suitable Boost versions should be included here, if they are not already
# contained in the FindBoost.cmake module provided with CMake. Hence, new
# versions should be added here as they are released...
set(Boost_ADDITIONAL_VERSIONS
  "1.65.1" "1.65.0" "1.65" 
  "1.64.0" "1.64" "1.63.0" "1.63" "1.62.0" "1.62" "1.61.0" "1.61" 
  "1.60.0" "1.60" "1.59.0" "1.59" "1.58.0" "1.58" "1.57.0" "1.57" 
  "1.56.0" "1.56" "1.55.0" "1.55" "1.54.0" "1.54" "1.53.0" "1.53" 
  "1.52.0" "1.52" "1.51.0" "1.51" "1.50.0" "1.50" "1.49.0" "1.49")
find_package(Boost 1.49 REQUIRED)

It appears that setting Boost_NO_BOOST_CMAKE or Boost_ADDITIONAL_VERSIONS after find_boost() has already been called resets the paths in the cache. So we cannot specify one manually.
