# BUILD_RPATH

Added in version 3.8.

A semicolon-separated list specifying runtime path (`RPATH`) entries to add to binaries linked in the build tree (for platforms that support it). By default, CMake sets the runtime path of binaries in the build tree to contain search paths it knows are needed to find the shared libraries they link. Projects may set `BUILD_RPATH` to specify additional search paths.

The build-tree runtime path will not be used for binaries in the install tree. It will be replaced with the install-tree runtime path during the installation step. See also the `INSTALL_RPATH` target property.

This property is initialized by the value of the variable `CMAKE_BUILD_RPATH` if it is set when a target is created.

This property supports `generator expressions`.

Other settings that affect the build-tree runtime path include:

- The `CMAKE_SKIP_RPATH` variable completely disables runtime paths in both the build tree and install tree.

- The `SKIP_BUILD_RPATH` target property disables setting any runtime path in the build tree.

- The `BUILD_RPATH_USE_ORIGIN` target property causes the automatically-generated runtime path to use entries relative to `$ORIGIN`.

- The `BUILD_WITH_INSTALL_RPATH` target property causes binaries in the build tree to be built with the install-tree runtime path.
