# Makefile for project PMEA linux/arm and linux/x86 builds. This makefile
# will build all the supported build flavors. You may override default flags
# for any or all build flavors by adding flags on the gnumake command line.
# For example:
#
#   cd $COMPONENTS_DIR/cdc/build/linux-arm-generic
#   make -f \
#     $COMPONENTS_DIR/tools/projects/pmea/build/linux/GNUmakefile \
#     opt_nosym USE_VERBOSE_MAKE=false
#
# Supported targets are:
#	all:            build all build flavors
#	list:           list all build flavors
#	source_bundles: builds the source bundle into $(SOURCE_OUTPUT_DIR)
#	<build_flavor>: build specified build flavor. More than one
#			<build_flavor> target can be specified.
#
# Note you must be in the cdc/build/linux-arm-generic or 
# cdc/build/linux-x96-generic device build directories before executing
# this makefile.
#
# Some cdc makefile defaults setup by this GNUmakefile:
#	COMPONENTS_DIR:          ../../.. (relative to device build directory)
#	USE_VERBOSE_MAKE:        true
#	CVM_BUILD_SUBDIR_SUFFIX: ""
#	CVM_BUILD_SUBDIR_NAME:   <build_flavor>$(CVM_BUILD_SUBDIR_SUFFIX)
#	SOURCE_OUTPUT_DIR:	$(COMPONENTS_DIR)/cdc/install/pmea_mr2
#	SUBMAKE_TARGETS:	Targets passed to submake, such as "bin"
#
# You can export CVM_BUILD_SUBDIR_SUFFIX from the shell if you always
# want a suffix. For example, a suffix of "_dir" is useful for easy
# cleanup of all build subdirs.
