Hi, It seems that cmake experts have left FreeType, so I try to respond you although I'm not an expert.
The shortest response would be: "CMakeLists.txt of FreeType does not support Debug build, so your attempt would not work". Nothing to say, the maintainers would welcome the proposal of patch, could you draft something? -- following is longer response. My first question is: cmake has any predefined compiler flag set for CMAKE_C_FLAGS_DEBUG? By brief checking of cmake manual, it seems that the effect of CMAKE_BUILD_TYPE "Debug" is only the reflection of the CMAKE_C_FLAGS_DEBUG option in the compilation. I cannot find any predefined set of CMAKE_C_FLAGS_DEBUG from the manual, and in my experiment on macOS, no typical debug options like "-g" is given to. I'm afraid default value of CMAKE_C_FLAGS_DEBUG is empty, so, nothing special happened (please try "make VERBOSE=1" to check the commands are being issued). In my impression, expecting "I set CMAKE_BUILD_TYPE to Debug, so the softwares should be built for debug mode" is something like a person wondering as "I changed the suffix of teacup.txt from txt to jpg, so I get teacup.jpg, but my browser does not show the picture of teacup. why?". In the package of the softwares whose CMakeLists.txt is ready for debug build, -DCMAK_BUILD_TYPE=Debug might work, but FT is not such.
