First Metis is an optional library, you shouldn't need it unless you are specifically in need for partitioning graphs.

If you really need it, then you need to fill the following variables : 

METIS_INCLUDE_DIR, the path to the directory containing METIS headers (*.h files)

and METIS_LIBRARY, the path to the .lib or .so file. 

Installing a library doesn't necessarily mean it will be automatically detected, especially if you install it in a non-standard path in linux. 

To make it (far) easier to use cmake, you can use the cmake-gui tool. This way you can see in one look what is missing (it is set to NOTFOUND) and easily fill it, and most of all you can see all the possible variables, which is pretty hard without it.

Hi,

I have checked all of this, I am currently having problems with the METIS
library. However, I have already installed it. But the directory is still
missing according to the message and the cmake-gui. Please see the message
below. Also, I want to mention that I am new when it comes to c++ and cmake.

CMake Warning at CMakeLists.txt:80 (find_package):
  By not providing "FindMETIS.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "METIS", but
  CMake did not find one.

  Could not find a package configuration file provided by "METIS" with any
of
  the following names:

    METISConfig.cmake
    metis-config.cmake

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