Creating binary with CMake removes runtime path


Note: if you don't want to modify the cmake scripts themselves, setting property around, you can launch you cmake with a directive asking to not remove the runtime path:
See "Variables that Control the Build", with variable: "CMAKE_SKIP_RPATH"

If true, do not add run time path information.

If this is set to TRUE, then the rpath information is not added to compiled executables.
The default is to add rpath information if the platform supports it. This allows for easy running from the build tree.
To omit RPATH in the install step, but not the build step, use CMAKE_SKIP_INSTALL_RPATH instead.

If the deliveries already contained the right runtime path, that directive will avoid cmake to do any modification to the current runtime path included in said deliveries.

cmake -DCMAKE_SKIP_RPATH=ON xxx.cmake


You should look at set_target_properties command and the property BUILD_WITH_INSTALL_RPATH

http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:set_target_properties


This works for CMake 2.8

 set_target_properties(foo PROPERTIES INSTALL_RPATH_USE_LINK_PATH TRUE)

where foo is the target you defined earlier:

 project(foo) add_executable(foo ...)  ... install(TARGETS foo DESTINATION bin)  ...

Before

% sudo make installInstall the project...-- Install configuration: ""-- Installing: /opt/mystuff/bin/foo-- Removed runtime path from "/opt/mystuff/bin/foo"

After

% sudo make installInstall the project...-- Install configuration: ""-- Installing: /opt/mystuff/bin/foo-- Set runtime path of "/opt/mystuff/bin/foo" to "/opt/zzyzx/lib:/opt/bar/lib/x86_64"
