+Subject: [PATCH] OpenCOLLADA/CMakeLists.txt
+
+Use CMAKE_BUILD_TYPE which can be overrided with custom distro types
+
+Adhere to GNU filesystem layout conventions. Not all distros and OSes
+have directories in the same locations and they define the
+GNUInstallDirs variables, so use those variables. Also, this enables
+multi lib installations.
+
+Define the version variables to enable SONAME versioning on the
+library files in case there is ABI changes in the future.
