[SOLVED] CMake on Raspberry Pi: Could NOT find Threads (missing: Threads

CMake on Raspberry Pi: Could NOT find Threads (missing: Threads_FOUND)

I'm trying to compile TrinityCore on Raspberry Pi. However, it cannot find Threads.

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97  (MESSAGE):
  Could NOT find Threads (missing: Threads_FOUND)
Call Stack (most recent call first):
  /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-2.8/Modules/FindThreads.cmake:166 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:54 (find_package)

-- Configuring incomplete, errors occurred!

Then I use "locate pthread.h". Here's a result:

/usr/include/mysql/my_pthread.h
/usr/include/pthread.h
/usr/local/include/ace/os_include/os_pthread.h
