It is much better to understand "why" than being told "how". On Ubuntu you will need corresponding -dev packages for all of the libraries dolphin needs. First you need to install the packages build-essential and cmake. Then you create a buildme folder inside the unpacked dolphin source. Change directory to the build me folder and run cmake (an enhanced make) in the directory above. So from inside the buildme folder run:
cmake ..
That will tell you why the build fails and what libraries you need (or look up what you need online). Then after cmake completes successfully you can run make, and it will build the software for you. I believe you can just run the binary directly no need to make install.
