What version of cmake do you have? "cmake --version" What exact command do you call cmake with? Are you setting -DCMAKE_BUILD_TYPE=Release|Debug|etc ? The easiest fix would be to just comment out that line 66 (with a hash character #), as it is fairly inconsequential. It downgrades the default optimization level from -O3 to -O2, for consistency with the now defunct qmake builds. On previous versions of cmake the default optimzation level for Release builds was -O3, but maybe that has changed recently. I am guessing that for some reason, your CMAKE_CXX_FLAGS_RELEASE is actually an empty string, so cmake is not "seeing" that as the 4th parameter to the string(REPLACE ) command. If I'm correct then I think that surrounding the variable reference on that line with double quotes might be the way to fix it properly. So this: ${CMAKE_CXX_FLAGS_RELEASE} would become this: "${CMAKE_CXX_FLAGS_RELEASE}" - Hans On Sun, Jan 16, 2022 at 6:45 PM Father Horton <fatherhorton@gmail.com> wrote: > I'm running Linux 20.2 in VirtualBox.

cmake 3.16.3 I commented out lines 64 and 66 and it builds with no problem. Thanks!
