You should be able to use custom Qt installation by setting CMAKE_PREFIX_PATH
to your Qt prefix

> m_button = new QPushButton("MyButton"); // where m_button is a

> delete m_button; // causes heap corruption debug assertion to fire

> A few other people have gone through similar issues but since they didn't use
> CMake, they simply ran Maya's moc utilities in a build step. I would like a
> solution where I can get CMAKE_AUTOMOC to run the custom Qt version.
