Hi. I’m trying to build Ganesha 3.4 (latest stable), and CMake output shows the following:

-- Looking for pthread.h

-- Looking for pthread.h - found

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed

-- Looking for pthread_create in pthreads

-- Looking for pthread_create in pthreads - not found

-- Looking for pthread_create in pthread

-- Looking for pthread_create in pthread - found

-- Found Threads: TRUE  

However CMake fails with the following in CMakeError.log. Not sure how to proceed. Please advise. Thanks.
