# Install generated and needed files to desired directories.

# 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.
