[CMake] RUNTIME_OUTPUT_DIRECTORY_<CONFIG> has no effect

[David Cole]

If you are having an "in source build" happen where you do not intend it to,
then you probably have an unintended CMakeCache.txt in the source tree. Get
rid of the build remnants from your source tree and try another out of
source build...

HTH,
David
