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

# - Check if the given struct or class has the specified member variable
|
|
# CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)
|
|
#
|
|
# STRUCT - the name of the struct or class you are interested in
|
|
# MEMBER - the member which existence you want to check
|
|
# HEADER - the header(s) where the prototype should be declared
|
|
# VARIABLE - variable to store the result
|
|
#
|
|
# The following variables may be set before calling this macro to
|
|
# modify the way the check is run:
|
|
#
|
|
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
|
|
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
|
|
# CMAKE_REQUIRED_INCLUDES = list of include directories
|
|
#
|
|
# Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h HAVE_TIMEVAL_TV_SEC)
