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

# - Find SWIG
|
|
# This module finds an installed SWIG. It sets the following variables:
|
|
# SWIG_FOUND - set to true if SWIG is found
|
|
# SWIG_DIR - the directory where swig is installed
|
|
# SWIG_EXECUTABLE - the path to the swig executable
|
|
# SWIG_VERSION - the version number of the swig executable
|
|
#
|
|
# The minimum required version of SWIG can be specified using the
|
|
# standard syntax, e.g. find_package(SWIG 1.1)
|
|
#
|
|
# All information is collected from the SWIG_EXECUTABLE so the
|
|
# version to be found can be changed from the command line by
|
|
# means of setting SWIG_EXECUTABLE
|
|
#
