CMAKE_SKIP_INSTALL_ALL_DEPENDENCY — CMake 3.8.1 Documentation

# CMAKE_SKIP_INSTALL_ALL_DEPENDENCY

Don’t make the `install` target depend on the `all` target.

By default, the `install` target depends on the `all` target. This has the effect, that when `make install` is invoked or `INSTALL` is built, first the `all` target is built, then the installation starts. If `CMAKE_SKIP_INSTALL_ALL_DEPENDENCY` is set to `TRUE`, this dependency is not created, so the installation process will start immediately, independent from whether the project has been completely built or not.
