Finding pyenv python package using CMake

Usage
3

A bit late to the party, but I ran into issues with CMake + pyenv on Windows today.
Based on the comment above, I added a few lines before calling find_package to set the ROOT_DIR, which solved the issue for me.

# Before looking for Python, check if pyenv is available
if(WIN32)
  find_program(PYENV_EXE NAMES pyenv.bat pyenv)

  if(PYENV_EXE)
    execute_process(
      COMMAND "${PYENV_EXE}" which python3
      OUTPUT_VARIABLE PYENV_PYTHON
      OUTPUT_STRIP_TRAILING_WHITESPACE
    )

    if(PYENV_PYTHON AND EXISTS "${PYENV_PYTHON}")
      get_filename_component(Python3_ROOT_DIR "${PYENV_PYTHON}" DIRECTORY)
      set(Python3_ROOT_DIR "${Python3_ROOT_DIR}" CACHE PATH "Root dir for Python3 from pyenv")
      message(STATUS "Used pyenv to find Python 3 in: ${Python3_ROOT_DIR}")
    endif()
  endif()
endif()

find_package(Python3 REQUIRED)
