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

# - SWIG module for CMake
# Defines the following macros:
# SWIG_ADD_MODULE(name language [ files ])
# - Define swig module with given name and specified language
# SWIG_LINK_LIBRARIES(name [ libraries ])
# - Link libraries to swig module
# All other macros are for internal use only.
# To get the actual name of the swig module,
# use: ${SWIG_MODULE_${name}_REAL_NAME}.
# Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify
# special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add
# special flags to all swig calls.
# Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify
# where to write all the swig generated module (swig -outdir option)
# The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used
# to specify extra dependencies for the generated modules.
# If the source file generated by swig need some special flag you can use
# set_source_files_properties( ${swig_generated_file_fullname}
# PROPERTIES COMPILE_FLAGS "-bla")
