@@ -67,6 +67,13 @@ from 3.12+ forward (3.15+ _highly_ recommended). If you set the minimum or
maximum version of CMake to 3.27+, then FindPython is the default (since
FindPythonInterp/FindPythonLibs has been removed via policy `CMP0148`).
Starting in pybind11 3.0, the new mode is the default, but we provide backward
compatible names (`PYTHON_*` vs. the new `Python_* names). Set the mode
explicitly to avoid the compatibility defines. You can specify this mode
explicitly by setting `PYBIND11_FINDPYTHON` to `COMPAT`, but if you are changing
your CMakeLists anyway, please just use the `ON` mode. A future release may
default to `ON`.
New FindPython mode
