Ah, I see, you've been making changes to the tests. I believe that

https://github.com/boostorg/preprocessor/blob/develop/test/CMakeLists.txt

should be relatively straightforward to figure out, provided you are familiar with
CMake. The full syntax of `boost_test` is

https://github.com/boostorg/cmake/blob/39443f18c03c4568fdf75bed3eaa802c26563663/include/BoostTest.cmake#L40-L47

boost_test( [TYPE type] [PREFIX prefix] [NAME name] [IGNORE_TEST_GLOBALS]
  SOURCES sources...
  ARGUMENTS args...
  LINK_LIBRARIES libs...
  COMPILE_DEFINITIONS defs...
  COMPILE_OPTIONS opts...
  COMPILE_FEATURES features...
)

but I don't think you need anything besides COMPILE_DEFINITIONS. This for
example

[ compile arithmetic.cpp : <define>BOOST_PP_LIMIT_MAG=512 : arithmetic_num_512 ]

translates to

boost_test(TYPE compile NAME arithmetic_num_512 SOURCES arithmetic.cpp COMPILE_DEFINITIONS BOOST_PP_LIMIT_MAG=512)
