In the Ninja generator we run all build rules from the top of the build
tree rather than changing into each subdirectory. Therefore we convert
all paths relative to the HOME_OUTPUT directory. However, the Convert
method on cmLocalGenerator restricts relative path conversions to avoid
leaving the build tree with a "../" sequence. Therefore conversions
performed for "subdirectories" that are outside the top of the build
tree always use full paths while conversions performed for
subdirectories that are inside the top of the build tree may use
relative paths to refer to the same files.
Since Ninja always runs rules from the top of the build tree we should
convert them using only the top-level cmLocalGenerator in order to
remain consistent. Also extend the test suite with a case that fails
without this fix.
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
Some native build tools, particularly those for cross compiling, may
have a limit on the length of the full path to an object file name that
is lower than the platform otherwise supports. This change allows the
limit to be set by the project toolchain file through the variable
CMAKE_OBJECT_PATH_MAX.
working, for both the result was always empty, since
cmMakefile::GetProperty() recognized it as a special property, constructed a
correct return value and called cmMakefile::SetProperty() with this list of
directories, which then didn't actually set the property, but applied it to
the internal vector of include/link directories. The following
getPropertyValue in cmMakefile::GetProperty() then still didn't find it and
returned nothing. Now for all special property the static string output is
used and its content is returned. I'm not sure it is the right way to fix
this problem but at least it seems to work and it fixes the Paraview3 build
