 To enable experimental GPU support see: [GPU/README.md](lib/TPP/GPU/README.md)
 
+In the example above, we are building both LLVM/MLIR and tpp-mlir in relese mode. You can easily change the build type by adopting the `-DCMAKE_BUILD_TYPE` option, e.g. `=DCMAKE_BUILD_TYPE=RelWithDebInfo`.

 ### Conda Environment
 
 Every modern Linux and MacOS system should be able to build our project without glitches, however, you may have an older OS or some special condisiont (cluster environment).
 As each operating system has its own package manager and package names, we opted for providing instructions for the user-level package manager ```conda```.
 This environment has been successfully tested on top of a Fedora Server minimal installation with less than 400 system-wide packages being installed.
