[Trilinos-Users] [EXTERNAL] Troubles with the install directories

  You need to use CMAKE_INSTALL_PREFIX to give the base install directory,
this value can be an absolute path. By default the library and include
directories are then <CMAKE_INSTALL_PREFIX>/lib and
<CMAKE_INSTALL_PREFIX>/include respectively. If you want to change those
from the default you can use Trilinos_INSTALL_LIB_DIR and
Trilinos_INSTALL_INCLUDE_DIR to change them, however, these values are
interpreted as relative to the CMAKE_INSTALL_PREFIX. This is a known
limitation that we've always had, but only recently discovered, and since it
makes certain installations possible we decided to embrace it. Looking at
the documentation for the Trilinos_INSTALL_*_DIR variables I see that it
does still indicate that you can use an absolute path. I will fix that as we
no longer support that case.
