Summary0006057: Patch to make it easier to ignore the OpenGL framework on Mac OS X
DescriptionAttached is a small patch to allow setting a flag on the cmake command line to ignore the OpenGL framework and use GL from X11 instead.
Steps To Reproduce
Additional InformationWhen buildign KDE against Qt/X11 on Mac OS X, it is desireable to use X11's libGL, rather than the system framework. Instead of having to muck with overriding the cmake variables, you can instead just build with "-DCMAKE_IGNORE_OPENGL_FRAMEWORK:BOOL=true" on the cmake command-line.

Hmm, the patch is obvious and shouldn't be able to break anything.

That said, I can't test that (I don't have a Mac) and I am not sure if we want to introduce variable for such purposes.
A simple way to improve this would be just to use OPENGL_IGNORE_FRAMEWORK as name for the variable:

set(OPENGL_IGNORE_FRAMEWORK TRUE)
find_package(OpenGL)

Could the COMPONENTS argument be used ?
find_PACKAGE(OpenGL COMPONENTS X11OpenGlLibs)

which would then disable searching for frameworks ?

Can you have a look at that ?

I really think the patch is too specific.

Does the following work too ?
set(CMAKE_FIND_FRAMEWORK NEVER)
find_package(OpenGL)
set(CMAKE_FIND_FRAMEWORK FIRST)

Or what about a new argument for the FIND_XXX() commands NO_FRAMEWORK_PATH ?

Sorry, I somehow missed the last time you commented on this... I'll answer in reverse. =)

I am nowhere near having a KDE build environment set up at the moment, so I can't test this, but this looks like something that would require changing every place in KDE where we find_package(OpenGL), which would be... awful. Especially since when building against Qt/Mac (as opposed to Qt/X11) we would *want* it to find the framework version, so then it would have to be parameterized.

as for this:

> set(OPENGL_IGNORE_FRAMEWORK TRUE)
> find_package(OpenGL)

That would seem reasonable. I'd be able to set it on the command-line too in my build scripts if I wanted to globally override things.

and:

> Could the COMPONENTS argument be used ?
> find_PACKAGE(OpenGL COMPONENTS X11OpenGlLibs)

...I guess has the same problem ias your more recent comment, we'd have to change every CMakeLists.txt file rather than having the option of choosing a default behavior on the command-line. (Unless the command-line would override both of those sets?)
