PPSSPP on Ubuntu

[cyclonmaster]

recently I get report like this when build latest git.

Code:

cyclonmaster@cyclonmaster-PC:~/ppsspp$ ./b.sh
-- Up-to-date: /home/cyclonmaster/ppsspp/build/assets/ui_atlas.zim
-- Installing: /home/cyclonmaster/ppsspp/build/assets/ppge_atlas.zim
-- Configuring done
CMake Error at CMakeLists.txt:480 (add_library):
  Cannot find source file:

    native/thread/threadpool.cpp

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx


-- Build files have been written to: /home/cyclonmaster/ppsspp/build

Is it normal?
