[eXpl0it3r]

Moving open points from #161 to here.

• [x] Add mention of SFML CMake Template see #160 and potential implementation
• [x] Update CMake tutorial, for using GNU Install Dirs (especially macOS), see https://github.com/SFML/SFML/issues/1563#issuecomment-466982693
• [x] Updating the french translation for this change https://github.com/SFML/SFML-Website/pull/161/commits/6570978b2d754dbe76f2dbed93e75e5350073add to have the same sentence structure in english and french.

Suggestions:

• Mentioning that sf::Keyboard::Scancode is an alias of sf::Keyboard::Scan::Scancode in inputs tutorial so that the code example is consistent with the corresponding paragraph.
• Updating the french translation for this change https://github.com/SFML/SFML-Website/pull/161/commits/6570978b2d754dbe76f2dbed93e75e5350073add to have the same sentence structure in english and french.

Hmmm, I'd lean more to leave it as is, but maybe I underestimation the confusion this can cause. It feels like a very technical thing to explain, plus I want to promote the usage of sf::Keyboard::Scancode.

Any other viewpoints/opinions?

On second thought, I think you are right. A beginner probably doesn't need this technical detail.
