## Install ##

## Mark header files for installation
install(
  DIRECTORY include/${PROJECT_NAME}
  DESTINATION ${CMAKE_INSTALL_PREFIX}/include
  FILES_MATCHING
  PATTERN "*.h" 
)

## Mark libraries for installation
install(TARGETS  
  ${PROJECT_NAME}
  EXPORT   "${PROJECT_NAME}Targets"
  LIBRARY  DESTINATION ${CMAKE_INSTALL_PREFIX}/lib/${PROJECT_NAME}
  INCLUDES DESTINATION ${CMAKE_INSTALL_PREFIX}/include
)

## Install the targets file associated with the lib
install(EXPORT 
  "${PROJECT_NAME}Targets"
  DESTINATION ${CMAKE_INSTALL_PREFIX}/lib/${PROJECT_NAME}/cmake/
)

## Configure the config file to have the necessary defines
configure_file(
  "${PROJECT_SOURCE_DIR}/cmake/${PROJECT_NAME}Config.cmake.in"
  "${PROJECT_BINARY_DIR}/cmake/${PROJECT_NAME}Config.cmake"
  @ONLY
)

## Finally install the config file so that cmake can find it
install(FILES
  "${PROJECT_BINARY_DIR}/cmake/${PROJECT_NAME}Config.cmake"
  DESTINATION ${CMAKE_INSTALL_PREFIX}/lib/${PROJECT_NAME}/cmake
)
