CPS package metadata involves a fair amount of passing around a particular set of values, as well as shared argument handling, which is only going to increase as additional features are added. In order to reduce code duplication (now and going forward), create a helper class to handle the shared argument parsing and to serve as a container to pass metadata values.

|
|
* \brief Generate files exporting targets from an install tree.
|
|
*
|
|
* 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.
