/** \class cmExportInstallPackageInfoGenerator
* \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.
