To avoid ambiguity on std::string assigment between the following two
cmProp cast operators:
* operator const std::string&() const noexcept
* operator cm::string_view() const noexcept
The new variable allows projects to define custom key=value pairs of
variables to be set in CPack cmake_install.cmake script invocations.
This allows install(SCRIPT|CODE) to be parameterized at runtime.
Merge use of SetFilterOption() into more abstract thread count
in cmArchiveWrite constructor.
libarchive defaulting of threads for threads == 0 seems to be
configuration dependent. Preemptively default thread count via
std::thread::hardware_concurrency().
Also allow negative values for the thread count in which case
the detected hardware concurrency is also used but the given
absolute thread count is used as an upper limit.
KWSys as of 2021-04-14 changed the return type of `SystemTools`
operations from `bool` to `Status`. Update our call sites.
This may improve error reporting accuracy in a few places.
a43783a08d CPackIFW: Fix parsing of name and version in component DEPENDS
f536e6f3fb CPackIFW: Remove redundant variable assignment
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5929
The DEPENDS or DEPENDENCIES arguments in a call to
cpack_ifw_configure_component() or cpack_ifw_configure_component_group()
specify a name and optionally a version constraint as a single string.
QtIFW also allows a colon (requires QtIFW 3.1 or later) or a hyphen to
separate the name and version. The version may optionally contain a
leading operator, with = being assumed when no operator is present.
The previous code was not handling : as a separator at all and was
erroneously dropping the version part when no operator was given.
Fix both of those non-conforming behaviors and also warn if trying
to use a hyphen in a name with a QtIFW version that isn't recent enough
to support it.
Fixes: #21697
In the case where the current path is a symlink to a directory, a
trailing slash causes the link to be dereferenced, which means that any
subsequent `FileIsSymlink` on it will return false.
Fixes: #21886
In d16830324f (CPackIFW: Improve warning and docs for show page list
option, 2021-02-14), code was added to report the current QtIFW version.
That code didn't check that there was a Generator object before using it,
resulting in a scanbuild warning about a potential null pointer dereference.
Add a check and output a more general warning message if we don't have
the current QtIFW version available to report.
