# CONFIGURE CORE PLATFORM MAKEFILE
#   This file is where we make platform and architecture specific 
#   configurations. This file can be specified for a generic architecture or can
#   be defined as variants. For instance, normally this file will be located in 
#   a platform specific subpath such as 
#
#        $(OF_ROOT)/libs/openFrameworksComplied/linux64
#
#   This file will then be a generic platform file like:
#
#        configure.linux64.default.make
#
#   Or it can specify a specific platform variant like:
#
#        configure.linuxarmv6l.raspberrypi.make

# PLATFORM DEFINES
#   Create a list of DEFINES for this platform.  The list will be converted into 
#   CFLAGS with the "-D" flag later in the makefile.  An example of fully 
#   qualified flag might look something like this: -DTARGET_OPENGLES2
#
#   DEFINES are used throughout the openFrameworks code, especially when making
#   #ifdef decisions for cross-platform compatibility.  For instance, when 
#   choosing a video playback framework, the openFrameworks base classes look at
#   the DEFINES to determine what source files to include or what default player 
#   to use.

# PLATFORM REQUIRED ADDONS
#   This is a list of addons required for this platform.  This list is used to

#   required addon header files as needed within the core. 
#
#   For instance, if you are compiling for Android, you would add ofxAndroid 
#   here. If you are compiling for Raspberry Pi, you would add ofxRaspberryPi 
#   here.

# PLATFORM CFLAGS

# PLATFORM LIBRARIES
#   These are library names/paths that are platform specific and are specified

#
#   PLATFORM_LIBRARIES are libraries that can be found in the library search 
#       paths.
#   PLATFORM_STATIC_LIBRARIES is a list of required static libraries.
#   PLATFORM_SHARED_LIBRARIES is a list of required shared libraries.
#   PLATFORM_PKG_CONFIG_LIBRARIES is a list of required libraries that are 
#       under system control and are easily accesible via the package 
#       configuration utility (i.e. pkg-config)
#
#   See the helpfile for the -l flag here for more information:

# PLATFORM CORE EXCLUSIONS
#   During compilation, these makefiles will generate lists of sources, headers

#   library. The PLATFORM_CORE_EXCLUSIONS is a list of fully qualified file 
#   paths that will be used to exclude matching paths and files during list 
#   generation.
#
#   Each item in the PLATFORM_CORE_EXCLUSIONS list will be treated as a complete
#   string unless teh user adds a wildcard (%) operator to match subdirectories.
#   GNU make only allows one wildcard for matching.  The second wildcard (%) is
#   treated literally.
