How to have multiple binary directories with CMake?

In my team we create a library. We use cmake and multiple third-party-libraries. We use the cmake command ExternalProject_Add to download and build the third-party libraries (which is done at compile time).

The problem is that when we clear the build directory to make a fresh build of our library, the third-party libraries are downloaded again, which is annoying.

I am wondering whether there is a way to specify another build directory for the third-party libraries so that they will be kind of "cached" ?

A solution could be to install your third-party libraries outside of the build directory, by changing the location of the install part, for example with option INSTALL_DIR of ExternalProject_Add().
