title: CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. in Ubuntu
body: <p>Is there anyone know this CMake build issue? I saw several similar question, but they are on Window</p>
  <p>In my case,</p>
  <ul>
  <li>OS: Ubuntu 16.04</li>
  <li>CMake version: 3.11</li>
  </ul>
  <p>When I write terminal below</p>
  <p><code>cmake -DROOT=&quot;/home/kyuhwanyeon/workspace/2000_CMSIS_ws/CMSIS_5&quot;   -DCMAKE_PREFIX_PATH=&quot;/home/kyuhwanyeon/gcc-arm-none-eabi-9-2020-q2-update/&quot;   -DCMAKE_TOOLCHAIN_FILE=&quot;/home/kyuhwanyeon/workspace/2000_CMSIS_ws/CMSIS_5/CMSIS/DSP/gcc.cmake&quot;   -DARM_CPU=&quot;cortex-m7&quot;   -G &quot;Unix Makefiles&quot; ..  </code></p>
  <p>Then the result,</p>
  <pre><code>CMake Error at /home/kyuhwanyeon/workspace/2000_CMSIS_ws/CMSIS_5/CMSIS/DSP/gcc.cmake:61 (add_link_options):
    Unknown CMake command &quot;add_link_options&quot;.
  Call Stack (most recent call first):
    /usr/share/cmake-3.11/Modules/CMakeDetermineSystem.cmake:94 (include)
    CMakeLists.txt:4 (project)
  
  
  CMake Error: CMake was unable to find a build program corresponding to &quot;Unix Makefiles&quot;.  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
  -- Configuring incomplete, errors occurred!
  
  </code></pre>
  <p>I already update build-essentials... But my Cmake doesn't find Unix Makefiles.</p>
