calibur must be compiled separately

[MathisGD]

like what is made here:

UniswapX/.github/workflows/test.yml

Lines 26 to 30 in 4c01ff0

	- name: Build Calibur submodule
	run: |
	cd lib/calibur
	forge build
	id: build-calibur

It should be documented in the readme:

UniswapX/README.md

Lines 64 to 78 in 4c01ff0

	# Usage
	```
	# install dependencies
	forge install
	# compile contracts
	forge build
	# run unit tests
	forge test
	# run integration tests
	FOUNDRY_PROFILE=integration forge test
	```

Alternatively, there could be an import file like this:

https://github.com/morpho-org/bundler3/blob/main/src/imports/MorphoImport.sol

With a foundry profile to have the right compilation parameters.
