On macOS, it is common to install packages like Mono through the third-party
package-manager Homebrew. This commit simply adds an additional path to
where Homebrew installs the Mono framework.
- Add option to print MSBuild's stdout and stderr instead of redirecting it. This can be enabled by setting the environment variable: Godot_DEBUG_MSBUILD=1
- Set (Csc/Vbc/Fsc)ToolExe environment variables to point to the batch files in Mono's bin directory when building with Mono's MSBuild.
- Set Mono's MSBuild as the default build tool on Windows.
- Generate projects with portable DebugType instead of full.
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
- Make sure to search the mono installation directory for the right architecture in the windows registry.
- Do not build GodotSharpTools directly to #bin dir. Instead build to the default output path and copy it. This way we avoid MSBuild adding files we don't want to #bin.
- Add hint path for MSBuild in OSX.
- Copy shared library on Unix if not statically linking.
- Use vswhere to search MSBuild and search for 14.0 tools version in the registry instead of 4.0.
- SCons will only fallback xbuild when msbuild is not found if 'xbuild_fallback=yes' is passed to the command.
- Use mono's assembly path as FrameworkPathOverride if using with system's MSBuild (not mono's fork).
- Cleanup.
