Summary0016051: Incorrect archive generated with CPACK_ARCHIVE_COMPONENT_INSTALL=ON with non-empty directory behind a symlink
Descriptioncmake_minimum_required(VERSION 3.0.0)

# generate files & folders
make_directory(${CMAKE_CURRENT_BINARY_DIR}/sample)
FILE(WRITE ${CMAKE_CURRENT_BINARY_DIR}/sample/dummy.txt "")
execute_process(
    COMMAND mkdir folder
    COMMAND ln -s folder alias
    WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/sample)

FILE(WRITE ${CMAKE_CURRENT_BINARY_DIR}/sample/folder/file.txt "")

# install 2 different components
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/sample/dummy.txt DESTINATION "." COMPONENT cmp1)

install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/sample/alias DESTINATION "." COMPONENT cmp2)
install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/sample/folder DESTINATION "." COMPONENT cmp2)

set(CPACK_ARCHIVE_COMPONENT_INSTALL ON)

include(cpack)

=======================

Run cmake, then cpack -G TGZ or ZIP. Open the archive of the second component (cmp2), and you get an error:

 >> unzip Project-0.1.1-Darwin-cmp2.zip
"
Archive: Project-0.1.1-Darwin-cmp2.zip
    linking: alias -> folder
checkdir error: alias exists but is not directory
                 unable to process alias/dummy.txt.
   creating: folder/
  inflating: folder/dummy.txt
finishing deferred symbolic links:
  alias -> folder
"
=======================

This append only if you specify CPACK_ARCHIVE_COMPONENT_INSTALL= ON and there is a file created into the folder (folder/file.txt). If the folder is empty, no error are generated by the unzip.

Seems to be appear when this feature have been introduced in CPack (cmake 3.4 release notes) :
The CPack module learned to package empty directories.

Often append if you package a bundle with frameworks...
