Yes you have probably only have the binaries and header files. KLEE's
**very** unfortunately doesn't support being built in this way.

Not properly no. The build system is a bit of a mess (piggy-backing
off another build system is just plain nasty). There are instructions
for doing this for Ubuntu in the pipeline [1] but long story short I
would like to switch to CMake because of the many benefits it offers.
I just don't have the time to do this right now.
