It's acknowledged that check state should not generally nest,
so it should be cleared when used, for example, in Find* module.
Also, add optional RESET argument to cmake_push_check_state().
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 patch adds two macros cmake_push_check_state() and
cmake_pop_check_state(), which can be used to save and restore
the contents of the CMAKE_REQUIRED_xxx variables.
