# =============================================================================
# C4D_MMD_Tool — Repository root workflow (dependencies + selected SDK plugin + optional installer)
# =============================================================================
# Typical usage (from repository root):
#   Recommended: CMake presets (see CMakePresets.json in this directory)
#     cmake --preset dev-windows
#     cmake --build --preset workflow-dev
#     cmake --preset package-windows
#     cmake --build --preset inno-installer
#   Or initial cache: cmake -S . -B _build_msvc -C cmake/initial_cache/dev.example.cmake
#   Manual:
#   cmake -S . -B _build_msvc -G "Ninja"
#   cmake --build _build_msvc --target cmt-deps-build
#   cmake --build _build_msvc --target cmt-sdk-configure
#   cmake --build _build_msvc --target cmt-sdk-build
# One-shot (configure + build plugin):
#   cmake --build _build_msvc --target cmt-workflow
#
# Root targets cmt-sdk-* / cmt-workflow do NOT use sdk_*/CMakePresets.json — they run
#   cmake -S <sdk> -B <binaryDir> -G ... and cmake --build <binaryDir> ...
# You may still use presets manually inside sdk_* (e.g. cmake --preset windows_vs2022_v143).
#
# Optional cache: CMT_SDK_DIR, CMT_SDK_BINARY_DIR, CMT_SDK_GENERATOR, CMT_SDK_MSVC_ARCH, CMT_SDK_TOOLSET,
#   CMT_SDK_SKIP_VS_A_AND_T (ON for Ninja/Xcode on Linux/macOS)
#
# Windows installer: cmt-package configures + Release-builds mmdtool in ALL sdk_* required by
# installer_script.iss, then runs ISCC. One command: cmake --build --preset inno-installer.
#
# Requires CMake 3.23+ (--build --preset for root repo presets). sdk_* may use a newer CMake.
