CMake module replacements for Tegra CUDA builds

This repository contains replacements for the old-style FindCUDA.cmake module and its helpers for use in cross-building CUDA applications for Jetson systems using Yocto Project/OpenEmbedded build tools.

They are direct copies from upstream CMake sources with minor modifications that fix issues with cross builds:

• Upstream FindCUDA.cmake attempts to invoke the C compiler with modified flags, which fails in the OE build environment.

• Recent JetPack releases containing CUDA 10.2 package the libcublas library differently from earlier releases.

Even though CMake's FindCUDA module has been deprecated in favor of CUDA language support and the FindCUDAToolkit module for some time, many applications still use FindCUDA.

Building

Prerequisite: You must have the cmake command in your PATH.

1. Run the ./configure script to create the Makefile.
2. make all

Installing

Once built, just use make install to install the default system root and prefix. You can specify an alternate root by passing DESTDIR=<path> on the command, and an alternate prefix with prefix=<path>.
