| Findraylib | ||
| ---------- | ||
| Defines an import target "raylib" based on the raylib_INCLUDE_DIR and raylib_LIBRARY variables. | ||
| The raylib_VERSION variable will be set to the found raylib version. | ||
| TGUI first searches for a config file in raylib_DIR, which is the recommended way to find raylib. | ||
| If this fails then this find script is used so that you can specify the include directory and library manually. | ||
| This script is intended for when you download the precompiled raylib release which lacks a cmake config file. | ||
