[CMake] Parallel jobs failed for cmake

[Igor Sobinov]

 Hello All,

Here is the small description of the issue:

OS: RHEL 6.6
cmake ver. 2.8.12.2
gmake ver. 3.81

I launch the build and got the following error:

make build_release -j5
make[1]: Entering directory `/home/igor/build_root/release_target'
make[1]: warning: jobserver unavailable: using -j1. Add `+' to parent make rule. So, make[1] reported that's job server is unavailable.

Here is typical process subtree of my make:

Hope it helps to find the issue

Regards, Igor
