INSTALL file not giving enough information.

[SwingOS]

INSTALL file doesn't give any information on how to do building.
I have perl, gcc and java installed in Windows 10.
I have changed the variables in /tools/setupenv.tcsh and /tools/setupenv.bash.
Then after that? It says if want to run AWT demo then execute this command. I tried CMD but didn't work.
Then what is this to build type make ? It doesn't work.

Please give detail info about how to build this and which IDE has been used to develop this.
Also try to add pictures of steps to build.
