title: How to specify the path where CMake is installed in the CMakeLists.txt
body: <p>I downloaded the portable CMake version from the official site, and installed it in my home directory（<code>~/usr</code>) because I don't have root or sudo permission.</p>
  
  <p><strong>How do I specify the path where CMake is installed in CMakeLists.txt, such as <code>~/usr/cmake-path/bin/cmake</code>?</strong></p>
  
  <p><strong>Note</strong>: I don't want to use the default version of CMake on the Linux system for it's too old (version 2.6)</p>
  
  <p>PS:</p>
  
  <p>I know of the variable <code>CMAKE_COMMAND</code> which may be useful for my question, but I don't know how to use it!</p>
