Meaning of env. variable $(CSF_OPT_INC) ?

Jean-Yves Brud's picture

Hello every body,

I got the following compilation error in project TKOpenGL
c1xx : fatal error C1083:

The problem was caused by the include $(CSF_OPT_INC) which is empty.
Removing this include solve the problem.

But what is the use of this variable ?

Thank you.
