Came up while testing debug/testing build for Windows. I'm not sure why
it didn't come up in earlier tests with similar config.
`tool_hugehelp.c` might indeed require `zlib.h` and without linking
`CURL_LIBS` to the `curltool` target, CMake doesn't seem to add detected
dependency headers to the compiler command.
