This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
* backends/vs: Only set platform_toolset if it isn't already set
* interpreter: set backend up after the compiler
Otherwise we won't be able to check which VS toolchain to use.
* docs/using-visual-studio: wrap lines
* docs: recommend the py launcher instead of python3 for windows
* set backend.environment when building a dummy version
* backends/vs: Add support for clang-cl with vs2017 and vs2019 backends
* backends/vs: Add support for ICL (19.x) with vs2015 and vs2017 backends
VS2017 requires the 'WindowsTargetPlatformVersion' property to be set.
We gather the version to use from the environment variable
'WindowsSDKVersion' that will be set by the VS developer command prompt.
VS2015 automatically picks up outputs from CustomBuild commands, which we
now use instead of CustomBuildStep commands, which do not get picked up
automatically.
