In principle this can equivalently be

find_package(Boost CONFIG REQUIRED COMPONENTS unit_test_framework
  PATHS
    "/home/linux/temp/boost_1_75_0/_x64"
    "D:/temp/boost_1_75_0/_x64")

although in the real project the paths probably shouldn't be hardcoded in
the
CMakeLists.txt file.

>    target_link_libraries(test ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})

This should be

target_link_libraries(test Boost::unit_test_framework)

The variables are old style CMake and shouldn't be used nowadays.
