| CMake Error in CMakeLists.txt: | |
| The COMPILE_FEATURES property of target "empty1" was evaluated when | |
| computing the link implementation, and the "CXX_STANDARD" was "98" for that | |
| computation. Computing the COMPILE_FEATURES based on the link | |
| implementation resulted in a higher "CXX_STANDARD" "11". This is not | |
| permitted. The COMPILE_FEATURES may not both depend on and be depended on | |
| by the link implementation. |
