The file (COPY_FILE) sub-command does not create such a dependency. See also the file (COPY) sub-command just below which provides further file-copying capabilities.
Installing Files — Mastering CMake
cmake.org › cmake › helpInstalling Files. ¶. Software is typically installed into a directory separate from the source and build trees. This allows it to be distributed in a clean form and isolates users from the details of the build process. CMake provides the install command to specify how a project is to be installed. This command is invoked by a project in the ...

cmake.org › cmake › helpCMake provides a file-based API that clients may use to get semantic information about the buildsystems CMake generates. Clients may use the API by writing query files to a specific location in a build tree to request zero or more Object Kinds. When CMake generates the buildsystem in that build tree it will read the query files and write reply files for the client to read.
