Microsoft Visual Studio 2019
----------------------------

The Visual Studio solution OpenCSG_vc2019.sln assumes that freeglut
is put in a freeglut/ subdirecty in the OpenCSG installation directory.
This works, for example, with the freeglut 3.0.0 MSVC package available
from https://www.transmissionzero.co.uk/software/freeglut-devel

The Visual Studio solutions automatically builds GLEW, the opencsg
lib, and the example. The solution allows to create both 64- and 32-bit
builds. To run the example, you must copy the freeglut.dll
into the directory example/Release/ or example/Debug/ where the
opencsgexample.exe has been built. Be sure to pick the correct
64- or 32-bit version of the dll.


Microsoft Visual Studio 6
-------------------------

The Visual Studio 6 solution OpenCSG.sln assumes that the original
GLUT for Windows is setup as described in
https://user.xmission.com/~nate/glut.html

The solution automatically builds GLEW, the opencsg lib, and the example.


Linux
-----

1) As prerequisites, you must install OpenGL development packages,
   GLEW, and, for the example, glut. The GLEW version provided with
   OpenCSG is not used automatically for building, but you can
   install GLEW from there if you like.
2) Just type 'make'. Maybe you must adjust the Makefiles in
   the src/ and the example/ directory for sucessful compilation.
3) The OpenCSG library will have been build in lib/, and the example
   "opencsgexample" will reside in the src/ directory. To run the
   opencsg example, you must ensure that libopencsg.so lib is in your
   LD_LIBRARY_PATH (e.G., one way to do this is to copy it to /usr/local/lib
   and running "ldconfig -v"). 'make install' is an automatic way to
   copy the build and the example into /usr/local (requires write access
   to /usr/local)
