+Linux dependencies
+==================
+install the following packages:  
+cmake cmake-curses-gui cmake-qt-gui libXi-dev libXmu-dev libglew-dev libboost-all-dev zlib1g-dev libqt4-dev qt4-dev-tools uuid-dev libgsl0-dev libsuitesparse-dev libqglviewer-dev
+
+Mac Dependencies
+=================
+To compile CGoGN on MAC 
+
+* install XCode and command line tools.
+* install Qt4 (4.8) and QtCreator
+* install (or build) libQGLViewer
+* install cmake (native or with homebrew)
+* install with homebrew : lzlib, glew, boost, suite-sparse
+
+To install suite-sparse package, you must first
+add the homebrew/science repository with the following command :
+	brew tap homebrew/science
+
+Compilation is the same as on Linux for CGoGN
+
+
+To compile CGoGN
+================
+ * first compile third-party libraries:
+
+	```
+	cd CGoGN/ThirdParty/build  
+	cmake ..  
+	make (-j x if you have x cores)
+	make install  
+	```
+
+	In debug mode:  
+	```
+	cd ../buildDebug  
+	cmake ..  
+	make  (-j x if you have x cores)
+	make install
+	```
+
+	Some options are available to not compile everything:
+	* WITH_ASSIMP  -> compile and use Assimp library 
+	* WITH_ZINRI -> compile and use Zinri library 
+	* WITH_PYTHONQT	-> needed by SCHNApps
+
+* then compile CGoGN (the libs are generated in CGoGN/lib and some examples in CGoGN/bin):
+
+	```
+	cd CGoGN/build  
+	cmake ..  
+	make (-j x if you have x cores)  
+	```
+
+	in debug mode:  
+	```
+	cd ../buildDebug  
+	cmake ..  
+	make  
+	```
+
+	Some options are available:
+
+	* BUILD_SHARED_LIBS  (F) experimental !
+	* ONELIB	-> allow compilation in one lib (libcgogn.a) instead of four.
+	* WITH_ASSIMP  -> use Assimp library (auto setted by third party compiling)
+	* WITH_ZINRI -> use Zinri library (auto setted by third party compiling)
+	* WITH_QT	-> to minimize dependencies and compilation time
+	* WITH_GLEWMX  -> to use GLEWMX (for VRJuggler users)
+
+* we can then compile SCHNApps and the provided plugins :
+	
+	```
+	cd CGoGN/SCHNApps/build  
+	cmake ..  
+	make (-j x if you have x cores)  
+	```
+
+	in debug mode:
+	```
+	cd ../buildDebug  
+	cmake ..  
+	make  
+	```
+
+Libraries are generated in lib/Release and lib/Debug
+Binaries are generated in bin/Release and bin/Debug
+
