CMake Error at src/pybind/CMakeLists.txt:4 (pybind11_add_module):
  Unknown CMake command "pybind11_add_module".
-- Configuring incomplete, errors occurred!

Workarounds

This can be fixed by manually include the pybind11Tools.cmake file which defines the function pybind11_add_module.

It seems that conan generated config.cmake file does not include pybind11’s tools definition file. Is this the designed behaviour or my settings might be wrong?

For me, there were two suitable include directories in pybind11_INCLUDE_DIRS (basically, a subdirectory and its parent). I wasn’t sure whether there are any circumstances under which one of them might be missing, so I decided to basically try both of them (it shouldn’t really hurt). This is why there are two alternatives, even though one of them should be enough.
