How can I instruct cmake to locate the SDL library in the desired location within my project?

edit

To instruct cmake to locate the SDL library in the desired location within your project, you can use the find_package command in your CMakeLists.txt file. Here's an example:

set(SDL2_DIR /path/to/sdl2)
find_package(SDL2 REQUIRED)

include_directories(${SDL2_INCLUDE_DIRS})
target_link_libraries(your_target ${SDL2_LIBRARIES})

In this example, replace /path/to/sdl2 with the actual path to your SDL installation directory. The find_package command will automatically search for the SDL library in the specified directory.

Then, use the include_directories command to add the SDL include directories to the include path of your target, and the target_link_libraries command to link against the SDL library.
