Add support for specifying CPS's supplemental `description` and
`website` attributes. Add ability to inherit these from the `project()`,
similar to how version information can be inherited.
Modify {export,install}(PACKAGE_INFO) commands to inherit version
information from the current project in situations where it seems
reasonable to do so. Add an option to explicitly request inheritance
from a specific project.
This leverages the recently added project(COMPAT_VERSION).
Consolidate InstallPackageInfo's bad arguments tests into only two test
cases that each test multiple invocations, rather than having a single
test per invocation. This makes them match the similar ExportPackageInfo
tests which were necessarily consolidated due to those testing many more
variants (due to differences in the respective interfaces). This will
simplify adding additional tests in the future.
Add import/export support and documentation for the SPDX_LICENSE
target property. A target's license can be specified by setting
this property to an SPDX license expression. CMake and CPS-format
export files generated with `export()` or `install()` will
retain the license information. CMake also imports the license
property for imported targets.
Closes: #26706
Rename the RunCMake/PackageInfo and RunCMake/CpsExportImport tests to
indicate that they cover CPS generated by the install command. This
opens space for similar tests that will cover CPS generation via the
export command.
