Rule #1: never use CMake older than the latest release!
Rule #2: if you die hard for old CMake, force use of the latest FindBoost.cmake
if (CMAKE_VERSION VERSION_LESS 3.12)
if (NOT EXISTS "${CMAKE_BINARY_DIR}/cmake/FindBoost.cmake")
message(STATUS "You are using CMake older than 3.10")
message(STATUS "FindBoost.cmake has likely been updated to detect
newer or even not yet released Boost")
message(STATUS "Downloading FindBoost.cmake from
https://gitlab.kitware.com/cmake/ release branch")
message(STATUS "The auto-download can be disabled with
GIL_DISABLE_FINDBOOST_DOWNLOAD=ON")
file(DOWNLOAD
"https://gitlab.kitware.com/cmake/cmake/raw/release/Modules/FindBoost.cmake";
"${CMAKE_BINARY_DIR}/cmake/FindBoost.cmake")
endif()
list(INSERT CMAKE_MODULE_PATH 0 ${CMAKE_BINARY_DIR}/cmake)
endif()
The rules work most of the time, unless a lil' bug sneaks in eg.

https://gitlab.kitware.com/cmake/cmake/issues/17701
Remember, FindBoost.cmake is *always* a step or two behind CMake release.
