Re-insert the semicolon which was removed during splitting.
Commit d777b8e7 (Genex: Allow relative paths in INSTALL_INTERFACE.,
2013-07-25) introduced the prefixItems method to allow relative paths
in the argument of the INSTALL_INTERFACE expression. That method was
buggy in that it did not re-introduce the semicolon separator in
the result.
This bug also affects paths which are already absolute in user code.
Xcode 2.1 through 4 supported $(CURRENT_ARCH) in a PBXFileReference
'path' value used in the "Link Binary with Libraries" build phase.
CMake uses this to reference object file locations on link lines to
bring in OBJECT library content. However, Xcode 5 now evaluates the
$(CURRENT_ARCH) reference in this context as "undefined_arch" so the
wrong path is given to the linker. There seems to be no alternative way
to produce an architecture-specific value in a PBXFileReference.
Fortunately Xcode 5 now also handles link dependencies for paths linked
through OTHER_LDFLAGS. For Xcode >= 5, move the OBJECT library object
file references from the link build phase to OTHER_LDFLAGS. We can
still show the object files in the source group listing in either case.
Xcode 5.0 now computes dependencies from files linked through
OTHER_LDFLAGS, so we no longer need the XCODE_DEPEND_HELPER hack to
re-link dependents when targets change.
In buggy code like
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/out.h.in
...)
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
...)
that has more than one rule to generate the same output CMake has always
used the first rule. However, since commit 2268c41a (Optimize custom
command full-path dependency lookup, 2013-08-06) we update the map from
output to cmSourceFile for every rule generating an output, effectively
keeping the last command instead of the first.
Fix this regression by checking for each map update if the output
already has an entry. If so, keep only the original entry. The VS 8
generator triggers this with a special case for generate.stamp rules
that differ between ZERO_CHECK and normal targets, so do not warn for
now. Leave a TODO comment for warning in the future.
Only one argument is required. Also avoid using the same variable name twice in
the input list and follow the convention used elsewhere for optional arguments.
