QtGui doesn't add linker dependency to libGLESv2
-
I am trying to take the Qt example from examples/gui/openglwindow/ and make it compile/run with CMake. However, when compiling, it fails with a bunch of
"error LNK2019: unresolved external symbol __imp_glClear"I can fix that by manually adding C:\Qt_install\lib\libGLESv2d.lib to the linker path, however, that's obviously not how CMake should work.
The CMakeLists is very simple:
@
PROJECT( oglwin )
CMAKE_MINIMUM_REQUIRED(VERSION 2.8.12 )
cmake_policy(SET CMP0020 NEW) # for Qt: auto-link to qtmain.libset(CMAKE_AUTOMOC ON)
find_package(Qt5Core REQUIRED)
find_package(Qt5Gui REQUIRED)SET(SOURCE
main.cpp
openglwindow.cpp
)
SET(HEADERS
openglwindow.h
)
ADD_EXECUTABLE( oglwin ${SOURCE} ${HEADERS} )
TARGET_LINK_LIBRARIES( oglwin Qt5::Core Qt5::Gui )
@Now as I mentioned before, my expectation would be that this automatically links to libGLESv2.lib (or libGLESv2d.lib), as I am using a Qt-build built with ANGLE.
(For that matter, I guess when on the desktop/opengl build, it should link to GL.lib [or whatever the system openGL lib is called]).Possibly in my case, it should also link to C:\Qt_install\lib\libEGLd.lib?
There are a few related topics around, for example this:
https://bugreports.qt-project.org/browse/QTBUG-29132
(where it says "fixed"), and one can follow that to gitorious:
https://codereview.qt-project.org/#change,53857Apparently what I'm trying to do should work, but it doesn't. Am I doing something wrong?
Thank you in advance!
