I just installed QT creator and I have an existing program with tons of C++ source files that I compiled before using CMakeLists and make on my Linux machine. I opened that project on Qt and went to Debug->Start debugging, but I get an error message "error while loading shared libraries: libmpc.so.3: cannot open shared object file: no such file or directory". However, this doesn't make sense because when I used `make` before, I never got this error. Am I doing something wrong?
