(Sadly, it appears that CMake would require that the test program be in a file of its own, rather than letting you embed it in the script, as autoconf does.)

Nope, it appears that CHECK_C_SOURCE_COMPILES() can take source code as an argument.  (I couldn't find the string "case-sensitive" in the CMake documentation, so I assume macro/function/etc. names are case-insensitive.)
