Cmake не мог найти кое -что для SDL3_TTF и SDL3_IMAGE, почему это? ⇐ C++

[Anonymous]

Хотя сборка / запуск < / code> происходит без каких -либо проблем для моих файлов CPP, но кто -нибудь может объяснить мне эти журналы Cmake специально Could NOT find SDL3_image и sdl3_ttf , давая эти предупреждения конкретно, поскольку им нужны эти внешние библиотеки, я думаю. Я использую проект Cmake с SDL3 , SDL3_IMAGE и SDL3_TTF источники в моем внешнем виде, которые непосредственно взяты из их текущего коммита. Я следовал процессу Cmake и файлам Cmake, упомянутым в их github install.md. Вот некоторые части журнала.1> [CMake] -- Configuring SDL3_image 3.2.1
