The CMake output in this case contains:

 -- Looking for Fortran cheev - not found

and the corresponding verbose information in CMakeFiles/CMakeError.log report that Fortran runtime symbols were not found at link time.

FindLAPACK tests the found libraries for usability before reporting success. When not using Fortran the static lapack/blas libraries cannot be used without manually bringing in the Fortran runtime libraries.

If I change the sample project to enable Fortran:

 project(test_lapack_blas Fortran C)

then I still get

 -- Looking for Fortran cheev - not found

but this time CMakeFiles/CMakeError.log contains

 /usr/lib/libblas.a(xerbla.o): In function `xerbla_': (.text+0x0): multiple definition of `xerbla_'
 /usr/lib/liblapack.a(xerbla.o):(.text+0x0): first defined here

which is the issue reported in 0012912.
