## This file handles cross-compilation configurations for aarch64,
|
|
## known as arm64. The objective of this file is to find and assign
|
|
## cross-compiler and the entire toolchain.
|
|
##
|
|
## This configuration works best with the buildroot toolchain. When using this
|
|
## file, be sure to set the TOOLCHAIN_PREFIX and CMAKE_SYSROOT variables,
|
|
## preferably via the CMake configuration command (e.g. `-DCMAKE_SYSROOT=<...>`).
|
|
##
|
|
## Currently, we recommend using buildroot toolchain for
|
|
## cross-compilation. Here is the link to download the toolchains:
