# OF ROOT
# The location of your root openFrameworks installation
# (default) OF_ROOT = ../../..
################################################################################
# OF_ROOT = ../../..
################################################################################
# PROJECT ROOT
# The location of the project - a starting place for searching for files
# (default) PROJECT_ROOT = . (this directory)

################################################################################
# PROJECT_ROOT = .
################################################################################
# PROJECT SPECIFIC CHECKS
# This is a project defined section to create internal makefile flags to
# conditionally enable or disable the addition of various features within
# this makefile. For instance, if you want to make changes based on whether
# GTK is installed, one might test that here and create a variable to check.
################################################################################
# None
################################################################################
# PROJECT EXTERNAL SOURCE PATHS
# These are fully qualified paths that are not within the PROJECT_ROOT folder.
# Like source folders in the PROJECT_ROOT, these paths are subject to
# exlclusion via the PROJECT_EXLCUSIONS list.

# Note: Leave a leading space when adding list items with the += operator

# PROJECT EXCLUSIONS
# These makefiles assume that all folders in your current project directory
# and any listed in the PROJECT_EXTERNAL_SOURCH_PATHS are are valid locations
# to look for source code. The any folders or files that match any of the
# items in the PROJECT_EXCLUSIONS list below will be ignored.
#
# Each item in the PROJECT_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.
#
# (default) PROJECT_EXCLUSIONS = (blank)
#
# Will automatically exclude the following:
#
# $(PROJECT_ROOT)/bin%
# $(PROJECT_ROOT)/obj%
# $(PROJECT_ROOT)/%.xcodeproj

# (default) PROJECT_LDFLAGS = -Wl,-rpath=./libs

# Note: Leave a leading space when adding list items with the += operator
################################################################################
# Currently, shared libraries that are needed are copied to the

# defined in your platform specific core configuration files. These flags are
# presented to the compiler BEFORE the PROJECT_OPTIMIZATION_CFLAGS below.
#
# (default) PROJECT_CFLAGS = (blank)
#
# Note: Before adding PROJECT_CFLAGS, note that the PLATFORM_CFLAGS defined in
# your platform specific configuration file will be applied by default and
# further flags here may not be needed.

# PROJECT OPTIMIZATION CFLAGS
# These are lists of CFLAGS that are target-specific. While any flags could
# be conditionally added, they are usually limited to optimization flags.
# These flags are added BEFORE the PROJECT_CFLAGS.

# PROJECT_OPTIMIZATION_CFLAGS_RELEASE flags are only applied to RELEASE targets.

# PROJECT_OPTIMIZATION_CFLAGS_DEBUG flags are only applied to DEBUG targets.
