CMake Error at CMakeLists.txt:3 (message):  
LV\_INSTALL\_LIBRARY\_DIR not set

Does the LV\_INSTALL\_LIBRARY means and LV\_SUPERBUILD\_DIR or LV\_CORE. I encounter the error when i try to build the enviroment based on Application as a source dir instead of LVSuperbuild or LVCore. Is this what this error means that it needs to build with either one of two and not from Application?
