pybind11 wrong while use cmake

[missximon]

The error looks like this:

#cd build && cmake .. && make && cd -

CMake Error at CMakeLists.txt:23 (find_package):
  By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "pybind11",
  but CMake did not find one.

  Could not find a package configuration file provided by "pybind11" with any
  of the following names:

    pybind11Config.cmake
    pybind11-config.cmake

  Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set
  "pybind11_DIR" to a directory containing one of the above files.  If
  "pybind11" provides a separate development package or SDK, be sure it has
  been installed.

but I have installed the pybind11 by pip install. what's problem and what should I do?

Pip doesn't install pybind11 search script to cmake. If I remember correctly, the conda version of pybind11 will do the correct job if your cmake is also installed by conda.

A simple workaround is open build/CMakeCache.txt and directly modify pybind11_DIR to the correct path, and then re-run cmake
