BUG: If a directory is specified on the command line that is not an existing build tree, we should still use any -G option that was given to set the generator.

ENH: Added Install test.  It is enabled when the CMAKE_INSTALL_PREFIX is CMake_BINARY_DIR/InstallTest.

BUG: Fixed implementation of long dependency list support.  The proxy target must have a corresponding file to work correctly.  Instead of using a proxy target, we now just list one line for each dependency and then print one copy of the build rule at the end.

ENH#61: cmake and ccmake now support passing the path to a CMakeCache.txt file as an argument.  Its settings will be loaded.
