title: Run make install command in cmake from another cmake file
body: <p>We have multiple libraries in different folder, The main application needs to build those libraries in other folders and install them to output folder and then the main application needs to link to libraries to build executable.</p>
  
  <p>I am able to build the libraries present in other folders using add_subdirectory() in a loop, but I am not able to install them to output folder by main cmake file. Could anyone help me out on this.</p>
