Comment (by lepus2589):

 Any minimal {{{CMakeLists.txt}}} file will do:

 {{{
 cmake_minimum_required(VERSION 3.20)

 project(DiscoverLAPACKE VERSION 1.0.0 LANGUAGES C)

 find_package(lapacke CONFIG REQUIRED)
 }}}

 Calling CMake with this file like this:

 {{{
 $ cmake -B ./build .
 CMake Error at CMakeLists.txt:5 (find_package):
   Could not find a package configuration file provided by "lapacke" with
 any
   of the following names:

     lapackeConfig.cmake
     lapacke-config.cmake

   Add the installation prefix of "lapacke" to CMAKE_PREFIX_PATH or set
   "lapacke_DIR" to a directory containing one of the above files.  If
   "lapacke" provides a separate development package or SDK, be sure it has
   been installed.
 }}}

 OK, it's in a non-standard location. Let's help CMake:

 {{{
 $ cmake -B ./build -D
 "lapacke_DIR=/opt/local/share/cmake/Modules/lapacke-3.12.0" .
 -- Could NOT find LAPACK (missing: LAPACK_DIR)
 }}}

 It doesn't throw an error, but doesn't discover lapack in the adjacent
 directory. Linking an actual project with this configuration would be
 impossible. Additionally providing the {{{lapack_DIR}}} variable on the
 command line won't help, because the {{{lapacke-config.cmake}}} overwrites
 it with an absolute path, which is wrong because it was moved.
