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

# This test will verify if CheckSymbolExists only report symbols available

# for linking that really are. You can find some documentation on this in
|
|
# bug 11333 where we found out that gcc would optimize out the actual
|
|
# reference to the symbol, so symbols that are in fact _not_ available in the
|
|
# given libraries (but seen in header) were reported as present.
|
|
#
|
|
# If you change this test do not forget to change the CheckCXXSymbolExists
|
|
# test, too.
