/** \class cmExportInstallFileGenerator
 * \brief Generate a file exporting targets from an install tree.
 *
 * cmExportInstallFileGenerator generates files exporting targets from
 * install an installation tree.  The files are placed in a temporary
 * location for installation by cmInstallExportGenerator.  One main
 * file is generated that creates the imported targets and loads
 * per-configuration files.  Target locations and settings for each
 * configuration are written to these per-configuration files.  After
 * installation the main file loads the configurations that have been
 * installed.
 *
 * This is used to implement the INSTALL(EXPORT) command.
