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.
NOTE: MUST USE GNU compliant version of sed
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' \
| xargs -0 gsed -i -f convert.sed \
&& rm convert.sed
