-This is caused because the return value of the createFrameSource_Video_GPU function should be a VideoFrameSource_GPU object.

-Subject: [PATCH] cmake/OpenCVGenPkgconfig.cmake: rework opencv.pc generation
-
-Using absolute path to locate the components in the "Libs:" field of the
-*.pc can badly break cross-compilation, especially when building
-statically linked objects.
-
-Indeed, pkg-config automatically replaces the '-I...' and '-L...' paths
-when the PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_LIBDIR environment
-variables are set [1]. This feature is very helpful and common in
-cross-compilation framework like Buildroot [2,3].
-
-When there are absolute paths in the *.pc files, pkg-config won't be
-able to do the path substitions for these paths when the afromentioned
-environment variables are set.
-In such case, since the prefix is the target one, not the sysroot one,
-these libraries' abolute paths will point to:
-- in the best case: a non-existing file (i.e. these files do not exists
-  on the host system;
-- at worst: the host system's libraries. This will make the linking
-  failed because these host system's libraries will most likely not be
-  build for the target architecture [4].
-
-So, this patch replace the components' absolute paths by the form:
-  -L<libdir> -l<libname>
-
-This way, the linker will be able to resolve each dependency path,
-whatever the kind of objects/build (shared object or static build) it
-is dealing with.
-
-Note that for static link, the library order does matter [5]. The order
-of the opencv components has been carefully chosen to comply with this
-requirement.
-
-Fixes #3931
