Notes

NOTE: -DCMAKE_SKIP_RPATH:BOOL=ON. With recent cmake-2.4, it should not be used. This cmake version should hand RPATHs issues correctly (set them in build-dir, remove them during installation). Setting CMAKE_SKIP_RPATH for this version would avoid RPATHs in build-dir too. This might link binaries against system-libraries (e.g. when a previous version of the package was installed) instead of the libraries which were created by the build.

Nevertheless, RPATH issues might arise when cmake was used improperly. E.g. installing a target with INSTALL(FILES ... RENAME ...) will not strip rpaths; in this case INSTALL(TARGETS ...) must be used in combination with changing the OUTPUT_NAME property.

NOTE: cmake has good documentation in two places:
