 > **Note:**
+* For RedHat 7.x, please use cmake3(>= 3.13.4) instead of cmake.
+* For debug build, use `-DCMAKE_BUILD_TYPE=Debug`.
+* For 32-bit build, use `-DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32`.
+* To enable Wayland support, use `-DBUILD_WAYLAND_SUPPORT=ON`.
 * If the build runs into errors like "collect2: fatal error: ld terminated with signal 9 [Killed]" due to out of memory, you could try  with reducing the number of threads in "make" command.
-* Debug build can be done by using `-DCMAKE_BUILD_TYPE=Debug`.
-* To enable Wayland support, you need to build the driver by using `-DBUILD_WAYLAND_SUPPORT=ON`.
