This new structure provides several benefits:
* Allows us to install multiple CMake projects in the same destination
dir (without include path conflicts).
- This makes shipping the trading algo sdk a trivial excercise. Simply
copy the lib and include dirs from the install dest. That's it!
* Puts us in a position to break up the monolithic libspark into smaller
modules, which are easier to manage.
Windows specific notes:
* Get rid of unnecessary script vs_filters.cmake
* Define WebsocketConnectionGateway directly in cs (instead of proto)
- The proto would no longer be in the include path passed to protoc.
Moving it to c# because there wasn't a compelling reason for it to
be a proto in the first place.
* Set spark output prefix to "lib" on windows
- So we get "libspark.dll" instead of "spark.dll", which conflicts
with the csharp lib, "Spark.dll".
* Copy libspark.dll to net8.0 & net8.0-windows in a single cmake build
target
fix build: Copy libspark to both dirs net8.0, net8.0-windows
