I think I wasn't clear.
I supposed that your CMakeLists.txt was taken from your project which
requires external project(s) so that

ExternalProject_Add(bullet PREFIX ${PROJECT_SOURCE_DIR})

should probably be replaced with something like:

ExternalProject_Add(bullet PREFIX ${PROJECT_SOURCE_DIR}/extdep/bullet)

in order to avoid mixing source of the various external projetcs you
integrate
with one another and with the main project.

May be you can send us your main CMakeLists.txt and/or describe
the directory structure you designed for your project and external projects?
