Malik, There is three different directories at play: 1. build directory (this is where you run cmake in) 2. the source directory (this is the deal.II download and contains CMakeLists.txt and source/ include/, etc.) 3. the install directory
All three directories can be anything you want. For example I might use: 1. ~/dealii-9.1.1/build/ 2. ~/dealii-9.1.1/ 3. ~/dealii-9.1.1-installed/ In that case I would: mkdir ~/dealii-9.1.1/build/ cd ~/dealii-9.1.1/build/ cmake -D CMAKE_INSTALL_PREFIX=~/dealii-9.1.1-installed/ ~/dealii-9.1.1/ make -j 4 make install If that doesn't work for you, tell us exactly what command you run in which directory.
