This is not a bug, but the feature! :)
RH DevToolset is not just an alternative compiler built on the side. It's libstdc++ is an LD script. The new C++11 (and above) symbols in your binary would be resolved via static library (built specially and shipped w/ DTS). However, old symbols (existed in the OS's shipped libstdc++) going to be resolved dynamically. That is why ldd shows you libstdc++ from the /usr/lib64! Also, it has Old C++ ABI by default... to make your modern C++ code compatible w/ old libstdc++ DSO.
This feature allows you to use modern C++ standards, and produce a binary which can be executed in the original OS (CentOS/RHEL) w/o any additional "redistributable" shared libraries.
JFYI, if you use strip, make sure you use it from DTS and not the "native" one (shipped in binutils from the OS)! Otherwise, really bad things can happen.

Can CMake automatically detect RH devtoolset-7? - Usage - CMake Discourse
June 4, 2021 - I am building on Centos 7, which natively has gcc 4.8.5, using CMake 3.16.6 and Ninja. My code requires gcc 7 so I specify RH devtoolset-7: -DCMAKE_CXX_COMPILER=/opt/rh/devtoolset-7/root/usr/bin/g++ My code checks the compiler version as follows: if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU") if (CMAKE_CXX_COMPILER_VERSION VERSION_LESS 5.4.0) message(FATAL_ERROR "g++ (GCC) version must be at least 5.4.0 (detected ${CMAKE_CXX_COMPILER_VERSION}). If on Centos 7, have you enabled Red...

Please note that the executable is called cmake3 on Red Hat 7 / CentOS7. On Red Hat 7 / CentOS7 mantid uses devtoolset-7. This means that you need to wrap your initial cmake command as scl enable devtoolset-7 "cmake3 /path/to/source".

For your information the only thing devtoolset is doing for you is providing a newer version for C/C++ Compiler and other tools like CMake, Make, etc.

Is it possible to pass kit-specific environment variables to CMake? · Issue #568 · microsoft/vscode-cmake-tools
October 24, 2018 - I am able to do this on Windows in Visual Studio 2017 using the CMakeSettings.json file, and there are hints in the documentation for CMake Tools that lead me to believe it is possible. However, if it is possible I cannot figure out how to do it. I have a kit defined as so: { "name": "GCC 7.3.1", "compilers": { "CXX": "/opt/rh/devtoolset-7/root/usr/bin/g++", "C": "/opt/rh/devtoolset-7/root/usr/bin/gcc" } }, and I tried using cmakeSettings like so: { "name": "GCC 7.3.1", "compilers": { "CXX": "/opt/rh/devtoolset-7/root/usr/bin/g++", "C": "/opt/rh/devtoolset-7/root/usr/bin/gcc" }, "cmakeSettings": { "environment": { "LIB_COMPILER_PREFIX": "gcc_7" } } }, However it doesn't seem to be working.
