Build destructions are crap

[Bazmundi]

Running destructions per block copy sees the "build" directory stuffed up higher than the ccp2py directory with the commensurate build failures.

Manually stepping through, so you're actually under the build directory when running the cmake, gets you:

(gcmc) asterion@MonstaPC:~/dev/cpp2py$ cd build/
(gcmc) asterion@MonstaPC:~/dev/cpp2py/build$ cmake -DCMAKE_INSTALL_PREFIX=INSTALL_DIR ../cpp2py
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

See also "/home/asterion/dev/cpp2py/build/CMakeFiles/CMakeOutput.log".

Ignoring the version warning, the fact the installing destructions do not include (it seems) setting up the "DESTINATION" means no confidence in this project.

Even setting INSTALL_DIR sees the same error.

Will it even build if I bother to sort out the crap build instructions?
