I have two files in one folder.
a.cc
b.cc
everyone have:
int main(int argc, char *argv[]) {
QCoreApplication application(argc, argv);
return 0;
}
One Cmake file with:
find_package(Qt5 COMPONENTS Core REQUIRED)
add_executable(a a.cc)
add_executable(b b.cc)
The problem is:
In a.cc my #include <QCoreApplication> is fine and everything okay. I can even change it to #include <QtCore/QCoreApplication> which is more convenient.
But
In b.cc my IDE "says" that #include <QCoreApplication> not exists and I should change it to #include <QtCore/QCoreApplication>.
During compile I get those errors:
b.cc undefined reference to `_imp___ZN16QCoreApplicationC1ERiPPci'
b.cc undefined reference to `_imp___ZN16QCoreApplicationD1Ev'
b.cc undefined reference to `_imp___ZN16QCoreApplicationD1Ev'Project is much bigger but I can't find anything that can relative with this problem.
Addition:
I know what is "undefined reference to" and I'm not a new to this problem
