Kitware Robot 9db3116226 Remove CMake-language block-end command arguments 
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

# - Find Java
# This module finds if Java is installed and determines where the
# include files and libraries are. This code sets the following
# variables:
#
# Java_JAVA_EXECUTABLE = the full path to the Java runtime
# Java_JAVAC_EXECUTABLE = the full path to the Java compiler
# Java_JAVAH_EXECUTABLE = the full path to the Java header generator
# Java_JAVADOC_EXECUTABLE = the full path to the Java documention generator
# Java_JAR_EXECUTABLE = the full path to the Java archiver
# Java_VERSION_STRING = Version of the package found (java version), eg. 1.6.0_12
# Java_VERSION_MAJOR = The major version of the package found.
# Java_VERSION_MINOR = The minor version of the package found.
# Java_VERSION_PATCH = The patch version of the package found.
# Java_VERSION_TWEAK = The tweak version of the package found (after '_')
# Java_VERSION = This is set to: $major.$minor.$patch(.$tweak)
#
# The minimum required version of Java can be specified using the
# standard CMake syntax, e.g. find_package(Java 1.5)
#
# NOTE: ${Java_VERSION} and ${Java_VERSION_STRING} are not guaranteed to be
# identical. For example some java version may return:
# Java_VERSION_STRING = 1.5.0_17
# and
# Java_VERSION = 1.5.0.17
#
# another example is the Java OEM, with:
# Java_VERSION_STRING = 1.6.0-oem
# and
# Java_VERSION = 1.6.0
#
# For these components the following variables are set:
#
# Java_FOUND - TRUE if all components are found.
# Java_INCLUDE_DIRS - Full paths to all include dirs.
# Java_LIBRARIES - Full paths to all libraries.
# Java_<component>_FOUND - TRUE if <component> is found.
#
# Example Usages:
# find_package(Java)
# find_package(Java COMPONENTS Runtime)
# find_package(Java COMPONENTS Development)
