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 module defines two macros:
|
|
# CMAKE_PUSH_CHECK_STATE()
|
|
# and
|
|
# CMAKE_POP_CHECK_STATE()
|
|
# These two macros can be used to save and restore the state of the variables
|
|
# CMAKE_REQUIRED_FLAGS, CMAKE_REQUIRED_DEFINITIONS, CMAKE_REQUIRED_LIBRARIES
|
|
# and CMAKE_REQUIRED_INCLUDES used by the various Check-files coming with CMake,
|
|
# like e.g. check_function_exists() etc.
|
|
# The variable contents are pushed on a stack, pushing multiple times is supported.
|
|
# This is useful e.g. when executing such tests in a Find-module, where they have to be set,
|
|
# but after the Find-module has been executed they should have the same value
|
|
# as they had before.
|
|
#
|
|
# Usage:
|
|
# cmake_push_check_state()
|
|
# set(CMAKE_REQUIRED_DEFINITIONS ${CMAKE_REQUIRED_DEFINITIONS} -DSOME_MORE_DEF)
|
|
# check_function_exists(...)
|
|
# cmake_pop_check_state()
