c++ - CMake: how to determine all the .DLL/.SO files that are need for an executable?

Question

Let's assume my program needs several DLL's to work. I should provide that DLLs to the user in my distribution. For now I need QtCore4.DLL, QtGui4.DLL, msvcp90.DLL, msvcr90.DLL, mylib.DLL, Kernel32.DLL...

Would be nice if CMake could get full list of DLLs (or .SO) files. Then I would remove items like "Kernel32.DLL" from that list and copy the DLLs to my distribution.

I can't guarantee the next build will be done on the same version of the Visual Studio, so hard-coding paths like "C:Program FilesMicrosoft Visual Studio 9.0VC edistx86Microsoft.VC90.CRT" or "E:Qt4.6.3" is not good for searching for the DLLs.

Thank you!

As suggested by Andre there is InstallRequiredSystemLibraries for finding/installing the correct C/C++ runtime. There is also BundleUtilities that can be used to find the other dependencies of your application, library and/or plugins.

It can never pick things up like runtime loaded plugins, but you can add them along with the library directories that should be used. In the most recent versions of CMake quite a few improvements have been made to make BundleUtilities more reliable on all platforms.
