Summary: Previously we would build all of the plugins by default and then only load some using the `LIBOMPTARGET_PLUGINS_TO_LOAD` variable. This patch renamed this to `LIBOMPTARGET_PLUGINS_TO_BUILD` and changes whether or not it will include the plugin in CMake. Additionally this patch creates a new `Targets.def` file that allows us to enumerate all of the enabled plugins. This is somewhat different from the old method, and it's done this way for future use that will need to be shared. This follows the same method that LLVM uses for its targets, however it does require adding an extra include path. Depends on https://github.com/llvm/llvm-project/pull/86868
The LLVM/Offload Subproject
The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.
The project is just starting and the design is still not ironed out. More content will show up here and on our webpage soon. In the meantime people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.
