follow $PREFIX
Build system promises installation to /usr/local, but binaries go to /usr/lib64 and /usr/bin and gettext stuff to /usr/share/locale
$ cmake ../ ... -- *** Building s63_pi *** -- *** Will install to /usr/local ***
$ sudo make install ... Install the project... /usr/bin/cmake -P cmake_install.cmake -- Install configuration: "Debug" -- Installing: /usr/lib64/opencpn/libs63_pi.so -- Installing: /usr/bin/OCPNsenc ... etc.
It would be really nice to have all by default in /usr/local like opencpn.
However, as of today CMakeLists supports the (non-obvious) PREFIX option, so cmake -DPREFIX=/usr/local should make the trick. Which possibly means that this bug could be closed (?)
