+HOW TO COMPILE
+---------------------------------------------------------
+CMAKE USERS
+.........................................................
+If you want to build the shared libraries under Windows using Visual
+Studio, you will have to use CMake version 3.4 or newer. If not, an
+earlier version will suffice. For a traditional out-of-source build
+under Linux, type something like
+
+ $ mkdir build # Create temporary build directory
+ $ cd build
+ $ cmake .. # CMake will determine all the necessary information,
+            # including the platform (32- vs. 64-bit)
+ $ make
+ $ make install
+ $ cd ..; rm -r build
+
+The default installation directory will be the top source directory,
+i. e. the binaries will go into bin/ and the libraries into lib/. You
+can change this behavior by calling CMake like this:
+
+ $ cmake .. -DCMAKE_INSTALL_PREFIX=/some/path/on/your/system
+
+With the INSTALL_BIN_DIR and INSTALL_LIB_DIR options, the directories
+the binaries & libraries will go in (relative to CMAKE_INSTALL_PREFIX)
+can be specified. For instance,
+
+ $ cmake .. -DINSTALL_LIB_DIR=lib64
+
+will install the libraries into a 'lib64' subdirectory in the top
+source directory. If INSTALL_INC_DIR is set, the public header files
+will be installed into the directory the value of INSTALL_INC_DIR
+points to. There is no default directory - if you want only the
+binaries and no headers, just don't specify INSTALL_INC_DIR, and no
+header files will be installed.
+
+Under Windows, it is probably easiest to use the CMake GUI interface,
+although invoking CMake from the command line as explained above
+should work as well.
+
+GCC USERS
+.........................................................
+There is a very simple makefile that compiles all libraries and exes
+from the root of the project run 'make'
+
+for 32 bits systems
+
+ $ make
+
+for 64 bits systems
+
+ $ make sq64
+
+VISUAL C++ USERS
+.........................................................
+Open squirrel.dsw from the root project directory and build(dho!)
