Using a CMakeLists.txt with the following content:
----------
cmake_minimum_required(VERSION 3.9)

find_package( cblas ) 
----------

results in:

CMake Error at /usr/lib64/cmake/lapack-3.7.0/lapack-targets.cmake:79 (message):
  The imported target "lapack" references the file

     "/usr/lib64/liblapack.so.3.7.0"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/lib64/cmake/lapack-3.7.0/lapack-targets.cmake"

  but not all the files it references.

There seems to be a missing link in "/usr/lib64":

liblapack.so.3.7.0 -> lapack/reference/liblapack.so.3.7.0


And touching the missing file "cblas-targets.cmake":

/usr/lib64/cmake/cblas-3.7.0/cblas-targets.cmake


results in successfull run of "find_package( cblas )"

[Comment 2 François Bissey 2018-09-25 11:27:20 UTC]

Version of cmake?

[Comment 3 justXi 2018-09-25 16:39:50 UTC]

Cmake 3.9.6 (stable from portage)

[Comment 4 François Bissey 2018-09-25 20:55:53 UTC]

Are you using blas from the science overlay or main tree. Furthermore what does 
eselect blas list 
report?

[Comment 5 justXi 2018-09-28 19:17:20 UTC]

I use all from main tree:

sci-libs/blas-reference-20161223
sci-libs/cblas-reference-20161223

virtual/blas-3.7
virtual/cblas-3.7

sci-libs/lapack-reference-3.7.0
virtual/lapack-3.7


result from "eselect blas list":
 [1]   reference *
