Comment (by kencu):

 Yeah -- if you install it first, and then run the tests, you don't need
 that extra bit.

 {{{-DCMAKE_BUILD_WITH_INSTALL_RPATH=ON}}} tells cmake to use the full,
 final library paths during the build.

 If the software has been installed already to the final location, then it
 finds the libraries and the test can build.

 If you have not installed the software yet, then all the libraries exist
 only in the build tree. And as the build is looking for them in their
 final locations, the linker can't find them.

 {{{
    configure.args-replace  -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON \
                             -DCMAKE_BUILD_WITH_INSTALL_RPATH=OFF
 }}}

 tells cmake to build it the normal, default way -- with rpaths referencing
 the build tree -- so that the build can find the libraries.

 Now my recollection is that somehow this still works even on Tiger (which
 doesn't use rpaths) -- I think by using the full path to the libraries in
 the build tree. But it's been a long while since I tested that specific
 point, so someone will have to re-verify it.

 At any rate, that block is the fix we use in many, many portfiles that use
 cmake to fix testing.

 We should change the cmake portgroups to stop forcing the wrong build
 strategy I think. If that change breaks some things, those things should
 be properly fixed instead of going back to the current default.
