[CMake] CMake-created Makefiles on a system without CMake

[William A. Hoffman]

CMake requires cmake to be installed during the build process.
If you move the build tree it will break.  There are various reasons
for this, and perhaps it should be a FAQ entry.

The main two reasons are:

- cmake does system introspection, finding headers, libraries, etc,
if you move the build file to a different machine all of that may be wrong.

- cmake uses its binaries to generate depend information at build time, not
cmake time.
