* **TARGETS**: Target or targets to install.
* **EXPORT**: Creates an export that can be installed with `install(EXPORT)`. Also creates a file at ${CMAKE_BINARY_DIR}/corrosion/<export-name>Corrosion.cmake that must be included in the installed config file.
* **EXPORT**: Creates an export that can be installed with `install(EXPORT)`. <export-name> must be globally unique.
Also creates a file at ${CMAKE_BINARY_DIR}/corrosion/<export-name>Corrosion.cmake that must be included in the installed config file.
* **ARCHIVE**/**LIBRARY**/**RUNTIME**/PUBLIC_HEADER: Designates that the following settings only apply to that specific type of object.
* **DESTINATION**: The subdirectory within the CMAKE_INSTALL_PREFIX that a specific object should be placed. Defaults to values from GNUInstallDirs.
* **PERMISSIONS**: The permissions of files copied into the install prefix.
