cmakeModules

This repository contains helpful CMake modules for a variety of Xilinx build flows.

Current release

The current release is meant to be used with the Xilinx Vitis 2022.1 tools.

There are two main toolchains:

(1) Vitis cross compiler toolchain (toolchain_vitis_crosscomp_arm.cmake)

(2) Clang cross compiler toolchain (toolchain_clang_crosscomp_arm.cmake)

The toolchains are invoked as most standard toolchains but with two additionally defined parameters (Arch, Sysroot).

$cmake .. -DCMAKE_TOOLCHAIN_FILE=<path to cmakeModules>/<target toolchain file> -DArch=<arm32|arm64> -DSysroot=<absoluate path to sysroot folder>

In both cases, the sysroot folder can be the default Vitis sysroot, a Petalinux generated sysroot or a standard Ubuntu-based sysroot like those built by PYNQ. In the case when you're working with more custom sysroots like Vitis or Petalinux, you should use the toolchain toolchain_clang_crosscomp_arm_petalinux.cmake which provides additional guidance to find the necessary libraries. Note that this file may need to be edited depending if you're using 2022.1 or an older tool version. See the toolchain_clang_crosscomp_arm_petalinux.cmake header for more information.
