If the dependent target sets the property to boolean false, ensure
that that appears in the debug report. Previously, the report
output contained whether the property was consistent among dependencies,
displaying 'TRUE', instead of the content of the property, which may
be 'FALSE'.
Return a std::pair from the consistentProperty method. This makes
it possible to make the return value for string types easier to
reason about. The return value of consistentProperty was previously
set to an empty static string to emulate a 'true' value for the caller
in commit 816b4a8a (cmTarget: Make consistentProperty
return consistent content., 2013-10-22). The pair makes the
consistency result properly typed.
Don't refer to 'both', but a 'mixture'. List all compatible interface
property types possible.
Add another test for a mixture of three compatibilities.
Revert the origin-tracking infrastructure from commit 98093c45 (QtAutoUic:
Add INTERFACE_AUTOUIC_OPTIONS target property., 2013-11-20). Use the
compatibility-tracking for compatible strings instead.
If two different dependencies require different AUTOUIC_OPTIONS,
cmake will now appropriately issue an error.
Set the minimum required version of CMake high enough to avoid the
warning for CMAKE_LEGACY_CYGWIN_WIN32. The warning appears on stderr
and breaks the expected output matching.
It is considered an error if the INTERFACE_INCLUDE_DIRECTORIES contains
a directory which does not exist, which indicates a programmer error
by the upstream, or a packaging error.
One of the RunCMake.CompatibleInterface tests also needs to be updated
due to this change. Non-existant includes were used in the test, but
are not needed.
