[SharedModel] Basic cmake support

[paulcam206]

Description

This change introduces cmake build support for the Shared Model. This allows us to independently build the Shared Model in a cross-platform way. As part of this, there were a number of code issues found that are fixed here (primarily from clang, which seems stricter than MSVC).

Tested configurations

• cmake/VS (Visual Studio 16 2019 / Windows SDK version 10.0.19041.0 / MSVC 19.28.29914.0 - Windows)
• cmake/gcc (GNU 10.3.0 - WSL)
• cmake/clang (Clang 9.0.1 - Windows and WSL)
• cmake/emscripten (emcc 2.0.18 - Windows and WSL)

Benefits

• Easy access to real clang tooling (e.g. clang-tidy)
• Different compilers catch different types of issues
• Necessary prerequisite to broader emscripten investigation

How do I build this thing?

• Windows + VS
  1. Install prerequisites
     • Install VS 2019
     • winget install cmake
  2. Run Developer Command Prompt for VS 2019 from start menu
  3. cd <ac root>\source\shared\cpp\ObjectModel
  4. cmake .
  5. cmake --build .
• Windows + clang
  1. Install prerequisites
     • winget install cmake
     • winget install llvm
  2. cd <ac root>\source\shared\cpp\ObjectModel
  3. cmake .
  4. cmake --build .
• Windows + emscripten
  1. Install prerequisites
     • winget install python
     • winget install cmake
     • winget install git
  2. Install emscripten
     1. git clone https://github.com/emscripten-core/emsdk.git <location to place emscripten SDK>
     2. cd <emsdk directory>
     3. git pull
     4. emsdk install latest
     5. emsdk activate latest
  3. cd <ac root>\source\shared\cpp\ObjectModel
  4. <emsdk directory>\emsdk_env.bat <- might not be needed depending on your environment
  5. emcmake cmake .
  6. cmake --build .
• WSL (Ubuntu) + gcc
  1. Install prerequisites: sudo apt update && sudo apt install cmake gcc
  2. cd <ac root>/source/shared/cpp/ObjectModel
  3. cmake .
  4. cmake --build .
• WSL (Ubuntu) + clang
  1. Install prerequisites: sudo apt update && sudo apt install cmake clang
     • You might need to change your compilers:
       • Environment vars:
         • export CC=/usr/bin/clang
         • export CXX=/usr/bin/clang++
       • Choose clang as your default C/C++ compiler:
         • sudo update-alternatives --config cc (choose clang)
         • sudo update-alternatives --config c++ (choose clang)
  2. cd <ac root>/source/shared/cpp/ObjectModel
  3. cmake .
  4. cmake --build .
• WSL (Ubuntu) + emscripten
  1. Install prerequisites: sudo apt update && sudo apt install cmake python3 git
  2. Install emscripten
     1. git clone https://github.com/emscripten-core/emsdk.git <location to place emscripten SDK>
     2. cd <emsdk directory>
     3. git pull
     4. emsdk install latest
     5. emsdk activate latest
  3. cd <ac root>/source/shared/cpp/ObjectModel
  4. source <emsdk directory>/emsdk_env.sh <- might not be needed depending on your environment
  5. emcmake cmake .
  6. cmake --build .

ooh -- build errors, that's exciting :)

UWP break is interesting -- complaining because existing max() macro def. Can force it not to be defined, but we're using min() macro def in XamlHelpers.cpp. Will fix tomorrow.

A couple questions but LGTM otherwise!

@jwoo-msft - could you fix up the iOS project for me? InternalID was moved into its own header file, InternalID.h, which needs to be referenced by the iOS project :)

Thanks!

@jwoo-msft - gentle ping :)
