Implement building app distributables using `pear build`

[jkcdarunday]

Introduction

Running pear build <key> <build directory> will:

1. Dump the app to the build directory
2. Generate a CMakeLists.txt from package.json if not included in the app code
3. Run bare-dev configure on the build directory
4. Run bare-dev build on the build directory

Testing

• [x] Test on Linux
  • Requires assets/linux/icon.png to exist in the app
• [x] Test on Windows
  • Requires assets/win32/icon.png to exist in the app
  • Requires assets/splash.png to exist in the app
  • Requires Visual Studio 17 2022 to be installed
  • Requires to be run using x64 Native Tools Command Prompt for VS 2022
  • Requires signing key to be generated and set in package.json
• [x] Test on Mac OS
  • Requires assets/darwin/icon.png to exist in the app
  • Requires assets/splash.png to exist in the app
  • Requires XCode utilities to be installed
  • Requires cmake to be installed (used brew)
  • Requires signing key to be generated, trusted, and set in package.json

Other Notes

• (RESOLVED) Workarounds were needed to be able to run bare-dev and its which dependency:
  • Added aliases for fs and path in the dependencies
  • Set global.process to require('bare-process')
  • Set the getuid and getgid functions to return a hardcoded id in global.process as they are not currently implemented
• pear build <channel> is not yet supported as I couldn't find a way to resolve channel to key within the cli
• pear dump <key> seems to print file changes regardless of outputter

Dependencies

• [x] Requires https://github.com/holepunchto/bare-dev/pull/11 to be merged and released
