package/taskd/0003-CMakeLists-use-pkg-config-uuid-detection.patch

   1 CMakeLists.txt: use pkg-config to detect uuid when possible
   2
   3 In order to take into account the libraries used by libuuid when
   4 building statically, using pkg-config is recommended. This patch
   5 therefore improves the CMakeLists.txt to use pkg-config to detect
   6 libuuid when pkg-config is available.
