+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
