# Environment variables are terrible. We use them for several purposes at once:
# 1. To pass configuration to build tools (WINEPREFIX, WINEDEBUG, etc)
# 2. To pass configuration to build system (ac_cv_*, CC, LD, CFLAGS, PERL, etc)
# 3. To pass configuration to the toolchain (LIBRARY_PATH, INCLUDE, LIB, etc)
# 4. To set PATH
#
# If we use a single `env` scratch space for storing all the above env, we hit
# two problems:
# * Some recipes use the MinGW toolchain while others use the MSVC toolchain
# * Autotools must be configured via env vars, but Meson wants native/cross files
#
# So we divide the env vars into five sections:
# 1. For build tools that are used regardless of toolchain: `env`
# 2. For the build system when using MinGW: `mingw_env_for_build_system`
# 3. For the build system when using MSVC: `msvc_env_for_build_system`
# 4. For the MinGW toolchain: `mingw_env_for_toolchain`
# 5. For the MSVC toolchain: `msvc_env_for_toolchain`
# Meson-specific configuration goes into `meson_properties`
