Setting BUILD_CLIENT=ON results in linker errors

Building clBLAS master on Fedora 25 with GCC 6.3.1, Mesa 17.1 git and ocl-icd 2.2.11. When BUILD_CLIENT=ON, make results in:

[tingxingdong]

u need to link with cblas. see https://github.com/clMathLibraries/clBLAS/wiki/Build section: CBLAS setup

[vedranmiletic]

Could you improve CMake configuration so that it fails if libblas-dev or equivalent is missing?

That is documented in https://github.com/clMathLibraries/clBLAS/wiki/Build-client,-samples,-gtest
