# CrossWinToARMLinux.cmake
#
# Set up a CMakeCache for a cross Windows to ARM Linux toolchain build.
#
# This cache file can be used to build a cross toolchain to ARM Linux
# on Windows platform.
#
# NOTE: the build requires a development ARM Linux root filesystem to use
# proper target platform depended library and header files.
#
# Configure:
# cmake -G Ninja ^
# -DTOOLCHAIN_TARGET_TRIPLE=armv7-unknown-linux-gnueabihf ^
# -DCMAKE_INSTALL_PREFIX=../install ^
# -DDEFAULT_SYSROOT=<path-to-develop-arm-linux-root-fs> ^
# -DLLVM_AR=<llvm_obj_root>/bin/llvm-ar[.exe] ^
# -DCMAKE_CXX_FLAGS="-D__OPTIMIZE__" ^
# -DREMOTE_TEST_HOST="<hostname>" ^
# -DREMOTE_TEST_USER="<ssh_user_name>" ^
# -C<llvm_src_root>/llvm-project/clang/cmake/caches/CrossWinToARMLinux.cmake ^
# <llvm_src_root>/llvm-project/llvm
# Build:
# cmake --build . --target install
# Tests:
# cmake --build . --target check-llvm
# cmake --build . --target check-clang
# cmake --build . --target check-lld
# cmake --build . --target check-compiler-rt-<TOOLCHAIN_TARGET_TRIPLE>
# cmake --build . --target check-cxxabi-<TOOLCHAIN_TARGET_TRIPLE>
# cmake --build . --target check-unwind-<TOOLCHAIN_TARGET_TRIPLE>
# cmake --build . --target check-cxx-<TOOLCHAIN_TARGET_TRIPLE>
# LLVM_PROJECT_DIR is the path to the llvm-project directory.
# The right way to compute it would probably be to use "${CMAKE_SOURCE_DIR}/../",
# but CMAKE_SOURCE_DIR is set to the wrong value on earlier CMake versions
# that we still need to support (for instance, 3.10.2).
