ghost compilation

Hello,

in a ui C++ project (with QWidget), if a C++ file with '.cpp' extension is included in the project (for instance 'file1.cpp'), and if a file with the same name but with extension '.c' (for instance 'file1.c') is present in the same directory as the '.cpp' file, but which is not included in the project, this file ('file1.c') is also  compiled during the build process. Strange isn't it?

This could be embarrassing when errors  happen during the compilation of this '.c' file, which was my case, but what happens when there are no error?

good luck,

best regards
