We have the IGNORE_VENDORED_DEPENDENCIES=ON option for this:

The only difference is that it does not run find_package(), but that could be added as an else here:

Which I'd expect to be necessary. I wonder why it worked without it for @aarlt (who added it) though?

Hey @chenrui333! Thanks for your contribution. Initially I created this IGNORE_VENDORED_DEPENDENCIES mechanism so that the solidity libraries can be easily used within vcpkg. The idea of that first version was, that a "root" cmake file will just search for the dependencies. However, we changed some internal libraries since then and I just did a small test here https://github.com/aarlt/cmake_vcpkg_solidity and it looks like that everything should just work, if you do what @cameel suggested. Just add an else to if (NOT IGNORE_VENDORED_DEPENDENCIES) in solidity/CMakeLists.txt, where you just ad find_package's for fmt, nlohmann_json and range-v3.
