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 protoype we expect is correct.
|
|
# check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)
|
|
# FUNCTION - The name of the function (used to check if prototype exists)
|
|
# PROTOTYPE- The prototype to check.
|
|
# RETURN - The return value of the function.
|
|
# HEADER - The header files required.
|
|
# VARIABLE - The variable to store the result.
|
|
# Example:
|
|
# check_prototype_definition(getpwent_r
|
|
# "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
|
|
# "NULL"
|
|
# "unistd.h;pwd.h"
|
|
# SOLARIS_GETPWENT_R)
|
|
# 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
|
|
# CMAKE_REQUIRED_LIBRARIES = list of libraries to link
