Because cmake's empty default for CMAKE_BUILD_TYPE (i.e. not
passinging any optimization flags i.e. use compiler defaults i.e.
unoptimized builds but also without the possibility to debug) is not
helpful for any use case, I habitually also pass
-DCMAKE_BUILD_TYPE=Release (or -DCMAKE_BUILD_TYPE=Debug when e.g. I
want a backtrace) to repositories using cmake. In the same sense I
habitually pass -j<n> to make because I rarely want to use only one
core of my multi-core CPU.
