hello, when i ccmake 8.2.0 with offscreen window in centos7. i install freeglut and osmesa, ccmake some configure:

```
VTK_HAS_OSMESA=ON
VTK_OPENGL_HAS_EGL = ON
VTK_OPENGL_USE_GLES = ON
VTK_PYTHON_VERSION =3.6
 VTK_MODULE_vtkglew_IS_SHARED = ON
VTK_USE_SYSTEM_GLEW =ON
VTK_USE_SYSTEM_HDF5 = ON
VTK_USE_SYSTEM_ZLIB = ON

```

The configure is success, but when execute “make -j8” is appear follow error :

```
