[CMake] [CPACK] Need explanation about `CPACK_CMAKE_INSTALL_PROJECTS' variable

[Tristan Carel]

Hi,

I don't really understand the purpose of the fourth argument named
`Project component' used to describe a project to install.
I felt lucky and tried to set a target name instead of the default
`ALL' value .. without success.

thx by advance.
