I'm using the Ninja generator/build system (i.e. one types ninja instead of make). Unfortunately, this leads to an issue with ExternalProject_Add. (I believe this actually is an issue of CMake's Ninja generator.)
The line I added here just tells CMake very explicitly that the library file is generated from this external project. For the usual Makefile generator, CMake automatically figures that out correctly, for Ninja it has to be stated explicitly.
This change should not affect the Makefile system at all.

I'd be glad if you would merge that in.
