CMake: avoid "make" in blas++ & lapack++

[nim65s]

Description

Replace make and make install by cmake --build and cmake --install, for cases where make is not available and/or CMAKE_GENERATOR is set to eg. Ninja.

In my case, this fix the following error:

[1631/6872] Performing build step for 'blaspp'
