Comment (by kencu):

 It looks like prior to the commit moving the cmake files in a post-
 destroot block, the lapack cmake config files were being installed like
 this:

 {{{
 x ./opt/local/lib/lapack/cmake/lapacke-3.12.0/lapacke-config-version.cmake
 x ./opt/local/lib/lapack/cmake/lapacke-3.12.0/lapacke-config.cmake
 x ./opt/local/lib/lapack/cmake/lapacke-3.12.0/lapacke-targets.cmake
 x ./opt/local/lib/lapack/cmake/lapacke-3.12.0/lapacke-targets-
 macports.cmake
 x ./opt/local/lib/lapack/cmake/lapack-3.12.0/lapack-config.cmake
 x ./opt/local/lib/lapack/cmake/lapack-3.12.0/lapack-config-version.cmake
 x ./opt/local/lib/lapack/cmake/lapack-3.12.0/lapack-targets.cmake
 x ./opt/local/lib/lapack/cmake/lapack-3.12.0/lapack-targets-macports.cmake
 x ./opt/local/lib/lapack/cmake/cblas-3.12.0/cblas-config.cmake
 x ./opt/local/lib/lapack/cmake/cblas-3.12.0/cblas-targets.cmake
 x ./opt/local/lib/lapack/cmake/cblas-3.12.0/cblas-config-version.cmake
 x ./opt/local/lib/lapack/cmake/cblas-3.12.0/cblas-targets-macports.cmake
 }}}

 so the problem is they are not installed in:

 {{{
 /opt/local/lib/cmake
 }}}
 they are being installed in:
 {{{
 /opt/local/lib/lapack/cmake
 }}}

 and in there, they can't be found by cmake.

 The reason they are being installed in that subdirectory is that the
 Portfile forces them to be installed there by setting this:
 {{{
  -DCMAKE_INSTALL_LIBDIR=${prefix}/lib/${name}
 }}}

 and so the cmake config files wind up tucked away in a special place with
 the default build where cmake can't find them. I presume the Portfile does
 that so the libraries are sequestered and other ports can also supply
 similar libraries without conflicting.

 I can't see an elegant solution immediately, other than manually moving
 the files in a corrected post-destroot block...
