find_package(Boost 1.71.0 REQUIRED COMPONENTS unit_test_framework) #
Optionally with CONFIG if you require a recent enough Boost
target_link_libraries(foo PUBLIC Boost::unit_test_framework)

Done. Nothing more than that. Plus it pretty much works for EVERY dependency

Your current solution uses variables: target_link_libraries(test
Replace that by the target, then you are fine

Tell them this: OOP is key. OOP in CMake means targets. Work with
targets and target_* functions, not e.g. `include_directories`

This is documented in the CMake docs, that CMake searchs the
<PREFIX>/lib/cmake folder:

Try to avoid touching  CMAKE_PREFIX_PATH in a CML unless you install
stuff in the same CMake to that path. Require users to export that env
variable instead.
This makes your files more portable. Having to set different env vars
for every software you install makes a mess.
