[cmake-developers] [CPack][BUG] Fail to package with CPACK_INSTALLED_DIRECTORIES

[CHEVRIER, Marc]

Hi,

To enable to handle various packages as part of the same project and to avoid to execute preinstall target before packaging, I rely on CPack variables CPACK_INSTALLED_DIRECTORIES and CPACK_INSTALL_COMMANDS.

Unfortunately, packaging is failing in the following conditions:

  *   Platform Windows (regardless generator: test done with “Visual Studio” and "Ninja”)
  *   Install command with PERMISSIONS read-only (like OWNER_READ)
  *   PROJECT command with LANGUAGES CXX (specifying LANGUAGES NONE is OK !??)

In this case, installed read-only files cannot be copied by CPack.

Attached is a CMakeLists.txt showing the problem:

  *   Target package-OK generates the expected package (no read-only permissions)
  *   Target package-KO fails to generate the package (same as previous one except read-only permissions)
