rdma-core make install failing

["ira.weiny" <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

I'm not sure what I'm doing wrong but make install seems to be deleting a
library and then complaining that it can't find it for installation...  :-/

After running build.sh I ran make install and get this error:

-- Up-to-date:
/nfs/site/home/iweiny/rdma-core/build/etc/libibverbs.d/cxgb3.driver
CMake Error at providers/cxgb3/cmake_install.cmake:62 (FILE):
  file INSTALL cannot find
    "/nfs/site/home/iweiny/rdma-core/build/lib/libcxgb3-rdmav2.so".
Call Stack (most recent call first):
  cmake_install.cmake:47 (INCLUDE)

make: *** [install] Error 1


While trying to figure out why cxgb3 was not building I noticed that actually
build.sh _is_ building the library.  And more importantly rebuilds it after
running make install as per below...


17:51:49 > ./build.sh

So checking for it...  yea there it is...

17:51:54 > ll build/lib/*cx*
-rwxr-x--- 1 iweiny intelall 138157 Feb 23 17:51 build/lib/libcxgb3-rdmav2.so*
-rwxr-x--- 1 iweiny intelall 184172 Feb 23 16:22 build/lib/libcxgb4-rdmav2.so*


Then I run make install again...

It fails as above and I look for the library and it is gone...

17:54:19 > ll lib/*cx*
-rwxr-x--- 1 iweiny intelall 184172 Feb 23 16:22 lib/libcxgb4-rdmav2.so*


What is going on here?

I'm really not familiar enough with cmake to see what majic softlink vs real
library installation is supposed to be going on here.
