Make the number of version components specified explicitly available.
Set variables for unspecified version components to "0" instead of
leaving them unset. This simplifies version number handling for find-
and config-modules. Also support a fourth "tweak" version component
since some packages use them.
Use the new-style error reporting mechanism to provide more context
information for a find_package call with a bad package name. When the
package is not required, issue a warning instead of an error.
The set_property command unsets a property if it is given no value. In
the case of GLOBAL properties, the cmake::SetProperty method would
replace a NULL value with "NOTFOUND". Instead it should be left as NULL
so that the property is unset as expected. Once it is unset the
get_cmake_property command will still report NOTFOUND while the
get_property command will return the empty string as documented.
When the -C or --build-config option is used to specify the
configuration to be tested by CTest, do not override it with the
configuration in which CTest is built.
A Mac OS X Framework should provide a Resources/Info.plist file
containing meta-data about the framework. This change generates a
default Info.plist for frameworks and provides an interface for users to
customize it.
This change cleans up the implementation of cmXCodeObject to avoid
un-escaping and re-escaping string values. There is no need to store
the string in escaped form. It can be escaped once when it is printed
out to the generated project file.
The recent fix to avoid including flags in dependency inferral also
dropped them from chaining of dependencies through targets. This fix
restores chaining of flags through known dependency lists while still
leaving them out of inferred dependency lists.
This change introduces a new algorithm for link line construction. The
order it computes always begins with the exact link line specified by
the user. Dependencies of items specified by the user are tracked, and
those that are not already satisified by the line are appended to it at
the end with minimal repeats. This restores the behavior of CMake 2.4
and below while still fixing some of its bugs. See issue #7546.
In cmComputeLinkDepends link items that look like flags (starting in
'-') should not be included in dependency inferral. They are not
libraries and therefore have no dependencies. They should just be
passed through to the final link line unchanged. See issue #7546.
This introduces the unset() command to make it easy to unset CMake
variables, environment variables, and CMake cache variables. Previously
it was not even possible to unset ENV or CACHE variables (as in
completely remove them). Changes based on patch from Philip Lowman.
See issue #7507.
