How to force CMake to relink project on resources change?

Question

I have a very simple C++ executable and a few .txt resource files. At build time I embedd the .txt files into the C++ binary via linker and then I load them at runtime (based on this answer). That works great.

My problem is relinking. Whenewer I change the .cpp source of my executable and run make, the project rebuilds itself. However, if I change a .txt file and run make, the binary doesn't relink. How can I force CMake to watch changes to my resource files (.txt) so that when those change the executable gets relinked to contain the newest .txt resource files?

Answer 1

You can set a source property called OBJECT_DEPENDS containing the path to your .txt file. The file to set this property for should be any source that is included in your target.
