Eclipse: warn if CMAKE_BINARY_DIR is subdir of CMAKE_SOURCE_DIR

Browse Source 
Eclipse doesn't handle this case well. When doing out-of-source builds
we create a linked resource which points to CMAKE_SOURCE_DIR, so the
user can browse the source dir in Eclipse. This is not possible
when the build dir is a subdir of the source dir.
