/** \class cmExportInstallCMakeConfigGenerator
* \brief Generate files exporting targets from an install tree.
*
* cmExportInstallCMakeConfigGenerator generates files exporting targets from
* an installation tree. The files are placed in a temporary location for
* installation by cmInstallExportGenerator. The file format is CMake's native
* package configuration format.
*
* 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.
