+\subsection cmake_other Collection of CMake Flags
+
+\li CMAKE_BUILD_TYPE: Build profile type defined above. Default is "release".
+\li CMAKE_INSTALL_PREFIX: Installation prefix path. Default is "/usr/local".
+\li ENABLE_PYTHON: Turn Python bindings on/off. Default is True.
+\li ENABLE_GR_<component>: Turn any top-level component on/off. Default is 
True for all.
+\li ENABLE_GR_CTRLPORT: Turn Building ControlPort. Default is True
+\li ENABLE_PERFORMANCE_COUNTERS: Turn performance counters on/off in runtime. 
Default is True.
+\li ENABLE_ORC: tells VOLK enable/disable use of Orc. Default is True.
+\li ENABLE_ASM: tells VOLK to use assembly files for proto-kernels if defined 
for the architecture. Default is True.
+\li ENABLE_STATIC_LIBS: build static library files. Default is False.
+\li CMAKE_TOOLCHAIN_FILE: A toolchain file to setup the CMake environment for 
cross-compiling.
+
+Here are som other potentially helpful CMake flags. These are to help you 
specifically locate certain dependencies. While the CMake scripts themselves 
should generally find these for us, we can use these to help direct CMake to 
specific locations if we have installed a different version elsewhere on the 
system that CMake doesn't know about.
+
+\li ICE_MANUAL_INSTALL_PATH: prefix of where ZeroC Ice was installed.
+\li QWT_LIBRARIES: shared library to use for Qwt (in the form 
<path>/libqwt.so).
+\li QWT_INCLUDE_DIRS: path to Qwt include files (e.g., /usr/include/qwt).
+\li PYTHON_EXECUTABLE: Location of the 'python' binary you want to use (e.g., 
/usr/bin/python2.7).
+\li PYTHON_INCLUDE_PATH: path to Python include files (e.g., 
/usr/include/python2.7).
+\li PYTHON_LIBRARY: Python's shared library location (e.g., 
/usr/lib/python2.7.so.1).
+\li Boost_INCLUDE_DIR: location of the 'boost' header file directory (e.g., 
/usr/include).
+\li Boost_LIBRARY_DIRS: location of the libboost-xxx.so files (e.g., /usr/lib)

+Other dependencies will have similar settings like these to properly locate 
them.
