CUDA_VISIBILITY_PRESET "hidden")
Since prior to CMake 3.18 the ``INTERPROCEDURAL_OPTIMIZATION`` property exists but is not working reliably, a manual user section around linking the legacy ``pybind11::lto`` target should look like this:
.. code-block:: cmake
# LTO/IPO: CMake target properties work well for 3.18+ and are buggy before
set(_USE_PY_LTO ON) # default shall be ON
if(DEFINED CMAKE_INTERPROCEDURAL_OPTIMIZATION) # overwrite default if defined
if(NOT CMAKE_INTERPROCEDURAL_OPTIMIZATION)
set(_USE_PY_LTO OFF)
endif()
endif()
if(CMAKE_VERSION VERSION_GREATER_EQUAL 3.18)
set_target_properties(example PROPERTIES
INTERPROCEDURAL_OPTIMIZATION ${_USE_PY_LTO})
else()
if(_USE_PY_LTO)
target_link_libraries(example PRIVATE pybind11::lto)
endif()
endif()
Instead of setting properties, you can set ``CMAKE_*`` variables to initialize these correctly.
