Building under linux (Fedora)

[xyz32]

Hello,

I am a bit confused about the instructions given in the wiki page on how to build FG under linux.

I have installed all the dependences posted in the wiki plus the ones that are needed but not document and I got FG to compile and run properly.
The thing I am confused about is (Free)GLUT. In order to make my compilation work I had to install it, but then reading the old Building FlightGear - Linux there is a line that reads:

For versions pre March 2008: (Free)GLUT or SDL (We recommend the use of SDL over Free/GLUT, however since March 2008, FreeGLUT as well as SDL are both considered deprecated, please only use --enable-osgviewer during configuration instead)

How to I enable this in the cmake environment? Or GLUT is back as a requirement?

Thank you.
