To use Qt in my projects with CMake, up until now all it seemed to
require was this:
find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})
But then I tried to use QTcpServer and QTcpSocket, and the compiles
failed because it couldn't find the include files.
Then I read through the FindQt4.cmake file that comes with CMake
2.8.4, and found that I could fix the problem with
find_package(Qt4 COMPONENTS QtCore QtGui QtNetwork REQUIRED)
But I'm confused that all my programs I built before I tried to use
networking had worked. I thought the first, simpler find_package
statement would just include everything by default. Is that wrong?
Did something change in recent CMake versions?
