FindBLAS.cmake and FindLAPACK.cmake will look in standard locations for libraries offering the standard BLAS and LAPACK APIs. For the former, the module will look for the Fortran implementation of the SGEMM function, for single-precision matrix-matrix products for general matrices. For the latter, the module searches for the Fortran implementation of the CHEEV function, for the calculation of eigenvalues and eigenvectors of complex, Hermitian matrices. These lookups are carried out internally by compiling a small program calling these functions and trying to link against the candidate libraries. If that fails, it signals that a compliant library is not available on the system.
Every compiler performs name-mangling of symbols ...
