# You can use notepad++ for syntax highlighting.
# Naming conventions:
#   WITH_*   : option to use an external package or not
#   ENABLE_* : option to use an internal feature/code or not
#   HAVE_*   : internal variable indicating if we have and are using something
#
# Example (build in subdir 'build' and install to source dir):
#   mkdir build
#   cd build
#   cmake -G"Unix Makefiles" -DINSTALL_TO_SOURCE:bool=ON ..
#   make install
#   cd ..
#   rm -rf build
