+From: Rudi Heitbaum <rudi@heitbaum.com>
+Date: Fri, 28 Mar 2025 09:31:40 +0000
+Subject: [PATCH] Allow build with CMake 4.0.0
+
+fixes deprecated cmake option and uses cmake 2.8.0 TARGET_FILE
+update cmake supported minimum versions to 2.8.0...3.10
+
+ref:
+- https://cmake.org/cmake/help/latest/policy/CMP0026.html
+
+CMake Error at .../CMakeLists.txt: (GET_TARGET_PROPERTY):
+  The LOCATION property may not be read from target "json_...".  Use the
+  target name directly with add_custom_command, or use the generator
+  expression $<TARGET_FILE>, as appropriate.
