Hi all,<br>
<br>
A colleague of mine reported a bug in our CMake-base build system when<br>
doing a parallel build of multiple targets where one of the targets is<br>
'test'.<br>
<br>
<quote><br>
Running 'make -j16 tMutex test' (or any test other than tMutex)<br>
for example will result in building tMutex in parallel to<br>
testing it.<br>
<br>
Expected behaviour is first building tMutex, followed by running<br>
the tests.<br>
</quote><br>
<br>
Is this indeed a bug? Either in our build system or in CMake?<br>
AFAIK it is not possible to define dependencies between the 'test'<br>
target and the target to build the test program. Correct?<br>
<br>
Best regards,<br>
Marcel Loose.<br>
