# This makefile is not a standalone makefile, but is called from the general one
# it contains targets specific to MacOS X

# it's possible to link OpenTTD dynamically and move the needed libs into the bundle
# this way it's possible to move the app around without thinking about libs on the computer it runs on
# dynamic linking is recommended for several reasons, specially because static linking makes issues with OpenTTD
# to setup the lib paths, a few flags needs to be set (default setup should work if the libs were installed with fink)
#
# OSX_LIB_PATH: this is the path to where the lib files are located on the compiling computer. (default /sw/lib/)
# OSX_LOCAL_LIB_PATH: is the path that the binary will use to search for the libs.
#	it's always an absolute path except when the keyword @executable_path is used, then it's the binary
#	it's important to remember that it's the binary and not the bundle, so to get the bundle path, use @executable_path/../../../

# the good thing about bundles is that you can keep extra files in them, so we keep lng files and a data dir in it
