From the point of view of the client application (for example Slicer), it shouldn't really matter if the project is retrieved from a build or installed tree. In fact, each project should be discovered using `find_package()`.

This would work if the variable `_DIR` is defined. It should be set with either the build or install dir. And since if should work if either the install or build tree. Using just the build tree should be enough.

Doing so would imply fixing the different CMake project we are working with.
