Add initial support for exporting (install only, for now) Common Package Specification (https://cps-org.github.io/cps/) format package descriptions. This has some limitations, such as not supporting generator expressions (as these cannot be portably exported), and only partially supporting transitive dependencies, but should be usable for at least some simple cases. (Actually, $<LINK_ONLY> is theoretically supportable, but is not yet implemented.) This still needs tests; these will be added in the next commit. Other potential improvements include support for language-specific compile definitions and inferring some package properties from project properties. Additionally, there is no module support yet; this is partly pending on having a tool agnostic format for providing the necessary information.

|
|
* cmExportInstallPackageInfoGenerator generates files exporting targets from
|
|
* an installation tree. The files are placed in a temporary location for
|
|
* installation by cmInstallExportGenerator. The file format is the Common
|
|
* Package Specification (https://cps-org.github.io/cps/).
|
|
*
|
|
* One main file is generated that describes the imported targets. Additional,
|
|
* per-configuration files describe target locations and settings for each
|
|
* configuration.
|
|
*
|
|
* This is used to implement the INSTALL(PACKAGE_INFO) command.
