# Build standard launcher.

# Setup make rules for building a standard launcher.
#
# Parameter 1 is the name of the rule. This name is used as variable prefix,
# and the targets generated are listed in a variable by that name. It is also
# used as the name of the executable.
#
# Remaining parameters are named arguments. These include:
# MAIN_MODULE  The module of the main class to launch if different from the
#     current module
# MAIN_CLASS   The Java main class to launch
# JAVA_ARGS   Processed into a -DJAVA_ARGS and added to CFLAGS
# EXTRA_JAVA_ARGS Processed into a -DEXTRA_JAVA_ARGS and is prepended
#     before JAVA_ARGS to CFLAGS, primarily to allow long string literal
#     compile time defines exceeding Visual Studio 2013 limitations.
# CFLAGS   Additional CFLAGS
# CFLAGS_windows   Additional CFLAGS_windows
# EXTRA_RCFLAGS   Additional EXTRA_RCFLAGS
# MACOSX_PRIVILEGED   On macosx, allow to access other processes
# OPTIMIZATION   Override default optimization level (LOW)
# OUTPUT_DIR   Override default output directory
# VERSION_INFO_RESOURCE   Override default Windows resource file
