Compile RAPP-API script does not install in proper paths

[klpanagi]

Due to the limitation of the rapp-api to assing install paths using CMAKE_INSTALL_PREFIX argument (here), installation and usage of the rapp-api fails.

The vm_compile_rapp_api.sh script correctly sets the CMAKE_INSTALL_PREFIX var, though rapp-api CMakeLists.txt does not properly handle this argument.

This issue is mostly related to the rapp-api, though as it affects rapp-robot-nao setup, it should be referenced here too.

Please consider this issue to be critical!

Scripts are using robot-api branch from rapp-api, and proper fixes are added there to handle CMAKE_INSTALL_PREFIX. See my comment to rapp-appi issue for more details.
