6 years ago make VERBOSE=1)-Wl,--verbose).I guess you have installed system libtbb.so.2.
To fix this, ensure that you call tbbvars.sh before "make" (it should setup "LIBRARY_PATH" environment variable).

6 years ago I've installed the last intel performance libraries 2018.1.163
So I ran manually
source /opt/intel/compilers_and_libraries_2018.1.163/linux/tbb/bin/tbbvars.sh intel64
before compiling. But I've got the same output

6 years ago What LIBRARY_PATH do you have?
$ echo ${LIBRARY_PATH}
/opt/intel/compilers_and_libraries_2018.1.163/linux/tbb/lib/intel64/gcc4.7Problem is here:
$ cat /opt/intel/tbb/lib/intel64/gcc4.7/libtbb.so
INPUT (libtbb.so.2)This occasionally redirects linker to system libtbb.so.2 if LIBRARY_PATH is not correct. This leads that you did't use Intel TBB binary really (if you have system one).
BTW, I believe this is very strange way to simulate versioning .so symbolic link (via linker scripts). True Linux way looks like this:
$ ll /usr/lib64/libtbb.so*
lrwxrwxrwx. 1 root root 11 Jun 11 2017 /usr/lib64/libtbb.so -> libtbb.so.2
-rwxr-xr-x. 1 root root 246056 Jun 11 2017 /usr/lib64/libtbb.so.2Perhaps this should be reported to TBB team (https://github.com/01org/tbb/issues)

6 years ago Sorry, Looks like LIBRARY_PATH doesn't work well.
Try to add this linker option instead:
-L/opt/intel/compilers_and_libraries_2018.1.163/linux/tbb/lib/intel64/gcc4.7For example:
cmake -DCMAKE_CXX_FLAGS="-Wl,-L/opt/intel/compilers_and_libraries_2018.1.163/linux/tbb/lib/intel64/gcc4.7" <...>Example of bad sequence (Fedora 26, -Wl,--verbose):
attempt to open /opt/intel/tbb/lib/intel64/gcc4.7/libtbb.so succeeded
opened script file /opt/intel/tbb/lib/intel64/gcc4.7/libtbb.so
attempt to open libtbb.so.2 failed
attempt to open /usr/lib/gcc/x86_64-redhat-linux/7/libtbb.so.2 failed
attempt to open /usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/libtbb.so.2 succeeded
libtbb.so.2 (/usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/libtbb.so.2)Good linker sequence:
attempt to open /opt/intel/tbb/lib/intel64/gcc4.7/libtbb.so succeeded
opened script file /opt/intel/tbb/lib/intel64/gcc4.7/libtbb.so
attempt to open libtbb.so.2 failed
attempt to open /opt/intel/tbb/lib/intel64/gcc4.7//libtbb.so.2 succeeded
libtbb.so.2 (/opt/intel/tbb/lib/intel64/gcc4.7//libtbb.so.2)
