Undefine functions in mm3d

[ErikaPistolesi1]

Hi!
I run cmake and make install on Linux Ubuntu 24.04 and got this error:

/usr/bin/ld: CMakeFiles/mm3d.dir/mm3d.cpp.o: in function TestLibAvailableCommands()': mm3d.cpp:(.text+0x4f5b): undefined reference to TestLulin_main(int, char**)'
/usr/bin/ld: CMakeFiles/mm3d.dir/mm3d.cpp.o: in function getAvailableCommands()': mm3d.cpp:(.text+0x15e6a): undefined reference to TestCmds_main(int, char**)'

Thank u!
