#
# add_jar(target_name
# [SOURCES] source1 [source2 ...] [resource1 ...]
# [INCLUDE_JARS jar1 [jar2 ...]]
# [ENTRY_POINT entry]
# [VERSION version]
# [OUTPUT_NAME name]
# [OUTPUT_DIR dir]
# )
#
# This command creates a <target_name>.jar. It compiles the given
# source files (source) and adds the given resource files (resource) to
# the jar file. Source files can be java files or listing files
# (prefixed by '@'). If only resource files are given then just a jar file
# is created. The list of include jars are added to the classpath when
# compiling the java sources and also to the dependencies of the target.
# INCLUDE_JARS also accepts other target names created by add_jar. For
# backwards compatibility, jar files listed as sources are ignored (as
# they have been since the first version of this module).
#
# The default OUTPUT_DIR can also be changed by setting the variable
# CMAKE_JAVA_TARGET_OUTPUT_DIR.
#
# Additional instructions:
#
# ::
#
# To add compile flags to the target you can set these flags with
# the following variable:
#
#
#
# ::
#
# set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
#
#
#
# ::
#
# To add a path or a jar file to the class path you can do this
# with the CMAKE_JAVA_INCLUDE_PATH variable.
#
#
#
# ::
#
# set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
#
#
#
# ::
#
# To use a different output name for the target you can set it with:
#
#
#
# ::
#
# add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)
#
#
#
# ::
#
# To use a different output directory than CMAKE_CURRENT_BINARY_DIR
# you can set it with:
#
#
#
# ::
#
# add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
#
#
#
# ::
#
# To define an entry point in your jar you can set it with the ENTRY_POINT
# named argument:
#
#
#
# ::
#
# add_jar(example ENTRY_POINT com/examples/MyProject/Main)
#
#
#
# ::
#
# To define a custom manifest for the jar, you can set it with the manifest
# named argument:
#
#
#
# ::
#
# add_jar(example MANIFEST /path/to/manifest)
#
#
#
# ::
#
# To add a VERSION to the target output name you can set it using
# the VERSION named argument to add_jar. This will create a jar file with the
# name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
# pointing to the jar with the version information.
#
#
#
# ::
#
# add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
#
#
#
# ::
#
# If the target is a JNI library, utilize the following commands to
# create a JNI symbolic link:
#
#
#
# ::
#
# set(CMAKE_JNI_TARGET TRUE)
# add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
# install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
# install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
#
#
#
# ::
#
# If a single target needs to produce more than one jar from its
# java source code, to prevent the accumulation of duplicate class
# files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
# to calling the add_jar() function:
#
#
#
# ::
#
# set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
# add_jar(foo foo.java)
#
#
#
# ::
#
# set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
# add_jar(bar bar.java)
#
#
#
# Target Properties:
#
# ::
#
# The add_jar() functions sets some target properties. You can get these
# properties with the
# get_property(TARGET <target_name> PROPERTY <propery_name>)
# command.
#
#
#
# ::
#
# INSTALL_FILES The files which should be installed. This is used by
# install_jar().
# JNI_SYMLINK The JNI symlink which should be installed.
# This is used by install_jni_symlink().
# JAR_FILE The location of the jar file so that you can include
# it.
# CLASS_DIR The directory where the class files can be found. For
# example to use them with javah.
#
# ::
#
# find_jar(<VAR>
# name | NAMES name1 [name2 ...]
# [PATHS path1 [path2 ... ENV var]]
# [VERSIONS version1 [version2]]
# [DOC "cache documentation string"]
# )
#
# This command is used to find a full path to the named jar. A cache
# entry named by <VAR> is created to stor the result of this command.
# If the full path to a jar is found the result is stored in the
# variable and the search will not repeated unless the variable is
# cleared. If nothing is found, the result will be <VAR>-NOTFOUND, and
# the search will be attempted again next time find_jar is invoked with
# the same variable. The name of the full path to a file that is
# searched for is specified by the names listed after NAMES argument.
# Additional search locations can be specified after the PATHS argument.
# If you require special a version of a jar file you can specify it with
# the VERSIONS argument. The argument after DOC will be used for the
# documentation string in the cache.
#
# ::
#
# install_jar(target_name destination)
# install_jar(target_name DESTINATION destination [COMPONENT component])
#
# This command installs the TARGET_NAME files to the given DESTINATION.
# It should be called in the same scope as add_jar() or it will fail.
#
# ::
#
# install_jni_symlink(target_name destination)
# install_jni_symlink(target_name DESTINATION destination [COMPONENT component])
#
# This command installs the TARGET_NAME JNI symlinks to the given
# DESTINATION. It should be called in the same scope as add_jar() or it
# will fail.
#
# ::
#
# create_javadoc(<VAR>
# PACKAGES pkg1 [pkg2 ...]
# [SOURCEPATH <sourcepath>]
# [CLASSPATH <classpath>]
# [INSTALLPATH <install path>]
# [DOCTITLE "the documentation title"]
# [WINDOWTITLE "the title of the document"]
# [AUTHOR TRUE|FALSE]
# [USE TRUE|FALSE]
# [VERSION TRUE|FALSE]
# )
#
# Create java documentation based on files or packages. For more
# details please read the javadoc manpage.
#
# There are two main signatures for create_javadoc. The first signature
# works with package names on a path with source files:
#
# ::
#
# Example:
# create_javadoc(my_example_doc
# PACKAGES com.exmaple.foo com.example.bar
# SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
# CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
# WINDOWTITLE "My example"
# DOCTITLE "<h1>My example</h1>"
# AUTHOR TRUE
# USE TRUE
# VERSION TRUE
# )
#
#
#
# The second signature for create_javadoc works on a given list of
# files.
#
# ::
#
# create_javadoc(<VAR>
# FILES file1 [file2 ...]
# [CLASSPATH <classpath>]
# [INSTALLPATH <install path>]
# [DOCTITLE "the documentation title"]
# [WINDOWTITLE "the title of the document"]
# [AUTHOR TRUE|FALSE]
# [USE TRUE|FALSE]
# [VERSION TRUE|FALSE]
# )
#
#
#
# Example:
#
# ::
#
# create_javadoc(my_example_doc
# FILES ${example_SRCS}
# CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
# WINDOWTITLE "My example"
# DOCTITLE "<h1>My example</h1>"
# AUTHOR TRUE
# USE TRUE
# VERSION TRUE
# )
#
#
#
# Both signatures share most of the options. These options are the same
# as what you can find in the javadoc manpage. Please look at the
# manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.
#
# The documentation will be by default installed to
#
# ::
#
# ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
#
#
#
# if you don't set the INSTALLPATH.

# create_javah(TARGET <target>
# GENERATED_FILES <VAR>
# CLASSES <class>...
# [CLASSPATH <classpath>...]
# [DEPENDS <depend>...]
# [OUTPUT_NAME <path>|OUTPUT_DIR <path>]
# )
#
# Create C header files from java classes. These files provide the connective glue
# that allow your Java and C code to interact.
#
# There are two main signatures for create_javah. The first signature
# returns generated files throught variable specified by GENERATED_FILES option:
#
# ::
#
# Example:
# Create_javah(GENERATED_FILES files_headers
# CLASSES org.cmake.HelloWorld
# CLASSPATH hello.jar
# )
#
#
#
# The second signature for create_javah creates a target which encapsulates
# header files generation.
#
# ::
#
# Example:
# Create_javah(TARGET target_headers
# CLASSES org.cmake.HelloWorld
# CLASSPATH hello.jar
# )
#
#
#
# Both signatures share same options.
#
# ``CLASSES <class>...``
# Specifies Java classes used to generate headers.
#
# ``CLASSPATH <classpath>...``
# Specifies various paths to look up classes. Here .class files, jar files or targets
# created by command add_jar can be used.
#
# ``DEPENDS <depend>...``
# Targets on which the javah target depends
#
# ``OUTPUT_NAME <path>``
# Concatenates the resulting header files for all the classes listed by option CLASSES
# into <path>. Same behavior as option '-o' of javah tool.
#
# ``OUTPUT_DIR <path>``
# Sets the directory where the header files will be generated. Same behavior as option
# '-d' of javah tool. If not specified, ${CMAKE_CURRENT_BINARY_DIR} is used as output directory.
