My apologies, I did what I did because of the following:
  537  sudo rm -r build/ && sudo rm -r experiments/
  538  ls
  539  git clone https://github.com/ilpincy/argos3-examples
  540  ls
  541  cd argos3-examples/
  542  mkdir build
  543  cd build/
  544  cmake -DCMAKE_BUILD_TYPE=Debug
[NOTE: the numbers represent the sequence of the commands as outputted from the 'history' command and were not actually typed for execution. Sorry for the confusion. =P]
ERROR:
CMake Error: The source directory "/Users/elliottapscott/Documents/Argos/argos3-examples/build" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Next sequence of commands to work around error:
  547  cd ..
  550  mv CMakeLists.txt ./build/
  551  cd build/
  552  ls
  553  cmake -DCMAKE_BUILD_TYPE=Debug

CMake Warning at CMakeLists.txt:33 (find_package):
  By not providing "FindGALIB.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "GALIB", but
  CMake did not find one.
  Could not find a package configuration file provided by "GALIB" with any of
  the following names:

  Add the installation prefix of "GALIB" to CMAKE_PREFIX_PATH or set
  "GALIB_DIR" to a directory containing one of the above files.  If "GALIB"
  provides a separate development package or SDK, be sure it has been
  installed.
