More windows-related nits

- use `!` instead of a `not` macro
- Don't build the `planparser` tool on windows; this uses unix commands to parse arguments.
- std::filesystem::path doesn't implicitly convert to std::string on msvc
- A shared library must specify export symbols (or set `CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS`) for a .lib file to be generated, which is required for things to link against said library.
- Can't use `*` (wildcard) on windows in a CMake command; use built-in CMake globbing instead.
