-The build processes uses CMake starting with UCX 3.0.
+The build processes uses configure and make.
 First, download the source code from [Source Forge][1].
 
     wget https://sourceforge.net/projects/ucx/files/ucx-latest.tar.gz
     tar -xzf ucx-latest.tar.gz
     cd ucx-latest
-    
-Then create a build directory and use cmake to create the build files,
-execute the build, and - optionally - install the files.
+
+Then execute ./configure with the options you like. You can get a list of
+all available options with ./configure --help. The recommended configuration
+for production builds is ./configure --release.
 
-    mkdir build
-    cd build
-    cmake ..
-    cmake --build .
-    sudo cmake --install .
+    ./configure --release
+    make
+    make check                 # only available when built with tests 
+    sudo make install
