* \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.
