[Mathieu Malaterre]

Package: flann
Version: 1.8.4-3

For some reason flann cannot discover gtest lib anymore:

-- Found the following Boost libraries:
--   mpi
--   system
--   serialization
--   thread
-- Could NOT find GTest (missing:  GTEST_LIBRARY GTEST_MAIN_LIBRARY)
CMake Warning at CMakeLists.txt:115 (message):
  gtest library not found, some tests will not be run


-- Try OpenMP C flag = [-fopenmp]
