[CMake] CMAKE_INSTALL_RPATH_USE_LINK_PATH is broken?

[Elizabeth Fischer]

Hello,

I'm using cmake 3.4.1.  I'm trying to compile libraries & executables with
an RPATH.  To that end, I use the following settings:


SET(CMAKE_SKIP_BUILD_RPATH  FALSE)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)
SET(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)


I then link in a lot of libraries.  However, ONLY ONE of the libraries gets
picked up to be used in the RPATH sent to the linker.  I can manually set
CMAKE_INSTALL_RPATH (that works).  But CMAKE_INSTALL_RPATH_USE_LINK_PATH
seems to be broken.

Interestingly, the one library it's willing to auto-generate an RPATH for
is the same library, whether it comes first or last in the link command
line.  The link command generated by CMake is shown below; it's clear that
many libraries are being linked in, but only one rpath is being generated.

HELP!!!!?
