[CMake] ENOEXEC exit code from ctest on FreeBSD

[Anoop C S]

Hi all,

While running tests from a wip branch[1] for socket_wrapper project I noticed the following output
on FreeBSD:

88% tests passed, 3 tests failed out of 25

Total Test time (real) =   2.54 sec

The following tests FAILED:
         21 - test_thread_echo_tcp_connect (Failed)

Stop.
make: stopped in /root/build

Following that I ran one among the failed tests from the above list using `ctest`:

# ctest -R test_thread_echo_tcp_connect
Test project /root/build
    Start 21: test_thread_echo_tcp_connect
1/1 Test #21: test_thread_echo_tcp_connect .....***Failed    0.07 sec

0% tests passed, 1 tests failed out of 1

Total Test time (real) =   0.07 sec

The following tests FAILED:
         21 - test_thread_echo_tcp_connect (Failed)
Errors while running CTest

# echo $?

# cmake --version
cmake version 3.10.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

I couldn't see any genuine errors from the test logs as such. Am I missing something? Since I am a
newbie to FreeBSD(and also to cmake) I would require some help to debug the reason for ENOEXEC exit
code.

Note:- The failed test cases uses threads.
