[CMake] Executable depending on all source files

Yes I know but git handling is "binary" either a file is handled
by git or not.

With CMake a source could be
  - to be added to some add_library (1 or several)
  - to be added to some add_executable (1 or several)
  - configure with configure_file(...)
  - simply installed with install(...)

Like I said even if the new file is a "cpp" file, should CMake add
it to add_executable or add_library or...

I know that you want to specify the "to be added" file spec using
a GLOB expression but then what we may need currently would be
a mechanism to cleanly trigger the refresh or the list of file.
FILE(GLOB ...) was not meant for that.

In my opinion if (I don't know if it's reasonable) we would want
to fullfil your need we would need something like a new variable type:

set(MYSOURCES "*.cpp" CACHE FILELIST)

then

cmake --refresh
would freshen such type of variables.
