CMake Error at CMakeLists.txt:4 (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.

CMake에서 find_package(pybind11 REQUIRED)를 추가한 경우 package를 찾지 못하는 경우가 있다.
보통 pybind11을 설치하면 된다고 생각하고 pip3 install pybind11 을 해보는데.... 안된다.

해결 방법

$ pip3 install pybind11-global
