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

# - Extract information from a subversion working copy
# The module defines the following variables:
# Subversion_SVN_EXECUTABLE - path to svn command line client
# Subversion_VERSION_SVN - version of svn command line client
# Subversion_FOUND - true if the command line client was found
# SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons
#
# The minimum required version of Subversion can be specified using the
# standard syntax, e.g. find_package(Subversion 1.4)
#
# If the command line client executable is found two macros are defined:
# Subversion_WC_INFO(<dir> <var-prefix>)
# Subversion_WC_LOG(<dir> <var-prefix>)
# Subversion_WC_INFO extracts information of a subversion working copy at
# a given location. This macro defines the following variables:
# <var-prefix>_WC_URL - url of the repository (at <dir>)
# <var-prefix>_WC_ROOT - root url of the repository
# <var-prefix>_WC_REVISION - current revision
# <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
# <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
# <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
# <var-prefix>_WC_INFO - output of command `svn info <dir>'
# Subversion_WC_LOG retrieves the log message of the base revision of a
# subversion working copy at a given location. This macro defines the
# variable:
# <var-prefix>_LAST_CHANGED_LOG - last log of base revision
# Example usage:
# find_package(Subversion)
# if(SUBVERSION_FOUND)
# Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
# message("Current revision is ${Project_WC_REVISION}")
# Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
# message("Last changed log is ${Project_LAST_CHANGED_LOG}")
# endif()
