Add the `CIRCTConfig.cmake` and `AddCIRCT.cmake` files to the list of
installed files. This mimics the behaviour implemented in MLIR, and
allows for CIRCT to be used out of tree (e.g. as part of the Moore
compiler, among other things).
Generally speaking, this should allow
cake -DCIRCT_DIR="<something>/lib/cmake/circt" myprojectdirectory, where <something> is
either a build or install area. Then in your project cmake file you can have:
find_package(CIRCT REQUIRED CONFIG)
This also updates the README to include some building information.
Lots of caveats:
- This is all experimental
- The actual tool isn't interesting yet.
- The naming is arbitrary and will likely change.
- Much of the cmake files were cargo culted from other places
because I don't know what I'm doing.
