> TARGET_LINK_LIBRARY(myexe ${LAPACK_LIB}$ ${BLAS_LIB}$)

You have extraneous '$' at the end of your variables reference
${LAPACK_LIB}$
should be
${LAPACK_LIB}
> =======================
>
> I have manually checked that BLAS and LAPACK are actually found.
> As explained in FindBLAS.cmake and Find.LAPACK.cmake, BLAS_LIBRARIES and
> LAPACK_LIBRARIES are lists containing paths to these libraries.
> I get the first entry in each of these lists and try to link with these
> entries (/usr/lib/libf77blas.so, /usr/lib/liblapack.so).
> But I obtain the following error message:
>
> ==================================================
>
> g++: error: /usr/lib/liblapack.so$: No such file or directory
> g++: error: /usr/lib/libf77blas.so$: No such file or directory
>
> ==================================================
>
so g++ is indeed right, look at the dollar sign at the end of .so files.
>
> But these files exist in my computer.

> Do you know where the problem come from?
