The system tools GetParentDirectory method no longer removes the root
path component. This fixes cmSystemTools::FileExistsInParentDirectories
to not infinitely loop at when GetParentDirectory stops at the root.
When SystemTools::GetParentDirectory was fixed to never remove the root
path component from a full path we violated an assumption made by
IsSubDirectory that eventually GetParentDirectory returns an empty
string. This led to an infinite loop if the potential parent directory
is empty, so we explicitly avoid that case.
The previous change to this method broke cases where the input path does
not exist. The SystemTools::GetParentDirectory method is redundant with
the more robust SystemTools::GetFilenamePath. This replaces its
implementation to just call GetFilenamePath.
The cmSystemTools::RenameFile method returns type bool, but its
implementation on Windows returns the result of an API function that
returns BOOL. This change avoids the compiler warning.
This extends the "-E" command line mode with a "rename old new"
signature. The new command atomically renames a file or directory
within a single disk volume.
This moves the cmGeneratedFileStream::RenameFile method implementation
into cmSystemTools. It works only within a single filesystem volume,
but is atomic when the operating system permits.
All KWSys C symbol names begin with the KWSYS_NAMESPACE defined at
configuration time. For ease of editing we write canonical names with
the prefix 'kwsys' and use macros to map them to the configured prefix
at preprocessing time. In the case of standalone KWSys, the prefix is
'kwsys', so the macros were previously defined to their own names.
We now skip defining the macros in the identity case so that the final
symbol names are never themselves macros. This will allow the symbols
to be further transformed behind the scenes to help linkers in special
cases on some platforms.
The add_external_project function separates its arguments with ';'
separators, so previously no command line argument could contain one.
When specifying CMAKE_ARGS, some -D argument values may need to contain
a semicolon to form lists in the external project cache.
This adds add_external_project argument LIST_SEPARATOR to specify a list
separator string. The separator is replaced by ';' in arguments to any
command created to drive the external project. For example:
add_external_project(...
LIST_SEPARATOR ::
CMAKE_ARGS -DSOME_LIST:STRING=A::B::C
...)
passes "-DSOME_LIST:STRING=A;B;C" to CMake for the external project.
Linking to a Windows shared library (.dll) requires only its import
library (.lib). This teaches CMake to recognize SHARED IMPORTED library
targets that set only IMPORTED_IMPLIB and not IMPORTED_LOCATION.
When an IMPORTED target provides no generic configuration and no match
for a desired configuration then we choose any available configuration.
This change corrects the choice when the first listed available
configuration does not really have a location.
CVS clients recognize file modifications only if a file's timestamp is
newer than its CVS/Entries line. This fixes intermittent failure of the
test on filesystems with low timestamp resolution by delaying before
creating a local modification.
Previously KWSys SystemInformation parsed this file assuming a strict
order and set of fields, but the order is not reliable. This
generalizes the implementation to support any order and extra fields.
The transitive link dependencies of a linked target must be followed in
its own scope, not in the scope of the original target that depends on
it. This is necessary since imported targets do not have global scope.
