kcss uses cmake. The compilation steps are similar to traditional configure, make, install.
$ cd ~/src/kcss
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
We build under subdirectory 'build' to keep source tree clean from intermediate binary and configuration files. You can build it directly on source tree as well.
