The latest commit of imspinner contains the damped_pring function, which is defined like this:
float damped_pring (double mass, double stiffness, double damping, double time, float a = PI_DIV_2, float b = PI_DIV_2) {
Since it isn't prefixed with inline, including this file into multiple .cpp files causes a multiple definition linker error like this:
/usr/lib/gcc/x86_64-pc-linux-gnu/11.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: libUntitledImGuiFramework.a(Global.cpp.o): in function `ImSpinner::damped_pring(double, double, double, double, float, float)':
Global.cpp:(.text+0x0): multiple definition of `ImSpinner::damped_pring(double, double, double, double, float, float)'; CMakeFiles/UntitledTextEditor.dir/Generated/main.cpp.o:main.cpp:(.text+0x0): first defined here
I reproduced this locally and on my CI workflows on both Windows(MSVC) and Linux(GCC).
