Verify that we do not need to explicitly disable: FLANN, SUNDIALS_MODELS, NLOPT

[Matthew Parno]

For the following CMake command, we should not have to specify “MUQ_USE_NLOPT:BOOL=OFF”,MUQ_ENABLEGROUP_MODELING_SUNDIALS_MODELS:BOOL, MUQ_ENABLEGROUP_UTILITIES_MULTIINDEX=ON, or MUQ_ENABLEGROUP_MODELING_FLANN:BOOL=OFF.

cmake3 \
  -D CMAKE_INSTALL_PREFIX=~/Installations/MUQ_INSTALL \
  -D MUQ_ENABLEGROUP_MODELING_SUNDIALS_MODELS:BOOL=OFF \
  -D MUQ_USE_NLOPT:BOOL=OFF \
  -D MUQ_ENABLEGROUP_SAMPLING_ALGORITHM=ON \
  -D MUQ_ENABLEGROUP_UTILITIES_MULTIINDEX=ON \
  -D MUQ_ENABLEGROUP_MODELING_FLANN:BOOL=OFF \
  -D MUQ_ENABLEGROUP_DEFAULT=OFF \
${MUQ_SRC_DIR}
