+From fa5ec96a94646492a3f908e12905b3e48a8e800b Mon Sep 17 00:00:00 2001
+From: Romain Naour <romain.naour@gmail.com>
+Date: Wed, 18 Apr 2018 20:24:13 +0200
+Subject: [PATCH] src/cpp: fix cmake >= 3.11 build
+
+CMake < 3.11 doesn't support add_library() without any source file
+(i.e add_library(foo SHARED)). But flann CMake use a trick that use
+an empty string "" as source list (i.e add_library(foo SHARED "")).
+This look like a bug in CMake < 3.11.
+
+With CMake >= 3.11, the new behaviour of add_library() break the
+existing flann CMake code.
+
+From CMake Changelog [1]:
+"add_library() and add_executable() commands can now be called without
+ any sources and will not complain as long as sources are added later
+ via the target_sources() command."
+
+Note: flann CMake code doesn't use target_sources() since no source file
+are provided intentionally since the flann shared library is created by
+linking with the flann_cpp_s static library with this line:
+
+target_link_libraries(flann_cpp -Wl,-whole-archive flann_cpp_s -Wl,-no-whole-archive)
+
+If you try to use "add_library(flann_cpp SHARED ${CPP_SOURCES})" (as it should
+be normally done), the link fail due to already defined symbol.
+
+They are building the shared version using the static library "to speedup the
+build time" [3]
+
+This issue is already reported upstream [2] with a proposed solution.
+
+Upstream status: Pending
+
+Fixes:
