[BUG]: Pybind11Tools.cmake not finding Python AND pybind11_add_module creates only executables

[Brandon-T]

Required prerequisites

• Make sure you've read the documentation. Your issue may be addressed there.
• Search the issue tracker and Discussions to verify that this hasn't already been reported. +1 or comment there if it has.
• Consider asking first in the Gitter chat room or in a Discussion.

What version (or hash if on master) of pybind11 are you using?

2.14.0 dev1

Problem description

find_package(PythonLibsNew ${PYBIND11_PYTHON_VERSION} MODULE REQUIRED ${_pybind11_quiet})

Doesn't seem to work in the latest CMAKE.

It should be find_package(Python3 ${PYBIND11_PYTHON_VERSION} MODULE REQUIRED ${_pybind11_quiet})

Otherwise it gives the error:

-- pybind11 v2.14.0 dev1
CMake Error at pybind11/tools/FindPythonLibsNew.cmake:265 (message):
  Python libraries not found
Call Stack (most recent call first):
  pybind11/tools/pybind11Tools.cmake:44 (find_package)
  pybind11/tools/pybind11Common.cmake:200 (include)
  pybind11/CMakeLists.txt:229 (include)

---

pybind11_add_module will also generate project_name.exe even though you specified SHARED as the argument.

Reproducible example code

add_subdirectory(pybind11)

IF(WIN32)
    
    # pybind11_add_module is broken on windows. Only generates EXE and never .dll even if SHARED is specified
    # Otherwise it works on all other platforms!

    add_library(${PROJECT_NAME} SHARED ${SRC_LIST})
ELSE()
    
    pybind11_add_module(${PROJECT_NAME} SHARED ${SRC_LIST})
ENDIF()

### Is this a regression? Put the last known working version here if it is.

Not a regression
