When following the build instructions in the README.md, I got dependency issues and needed to build with the following argument:
$ cmake -DMODBUS_VENDORED_DEPS=ON .. $ cmake --build . ...

PS - I'm building on WSL2 - Ubuntu 22.04 using cmake 3.22 and gcc 9.5 :)
I was able to build successfully with MODBUS_VENDORED_DEPS=ON and MODBUS_BUILD_TESTS=OFF.
MODBUS_VENDORED_DEPS=ON
MODBUS_BUILD_TESTS=OFF
Updated Cache2
