Missing references trying to compile shm-dev branch

[hrhelena]

Hi , Now it compiles without errors but when i tested like this
ld -lLibOpenHevcWrapper --verbose

there are still some missing references.

attempt to open //usr/local/lib/libLibOpenHevcWrapper.so succeeded
-lLibOpenHevcWrapper (//usr/local/lib/libLibOpenHevcWrapper.so)
libm.so.6 needed by //usr/local/lib/libLibOpenHevcWrapper.so

ld: warning: cannot find entry symbol _start; defaulting to 000081f0

I checked from the CMakeError.log and i've found this

Determining if the function pthread_create exists in the pthreads failed with the following output:

It is looking for -lpthreads instead of -lpthread could it be that the problem?
