# Install generated and needed files to desired directories.
# On GNU/Linux and BSDs, there are some standard directories that contain extra
# libraries and header files. These directories (often /usr/local/lib and
# /usr/local/include) are for libraries that are installed manually
# (without a package manager). We'll use /usr/local/lib/raysan5 and /usr/local/include/raysan5
# for our -L and -I specification to simplify management of the raylib source package.
# Customize these locations if you like but don't forget to pass them to make
# for compilation and enable runtime linking with -rpath, LD_LIBRARY_PATH, or ldconfig.
# Hint: add -L$(RAYLIB_INSTALL_PATH) -I$(RAYLIB_H_INSTALL_PATH) to your own makefiles.
# See below and ../examples/Makefile for more information.
# TODO: Add other platforms. Remove sudo requirement, i.e. add USER mode.
