Re: [VOLK] Release 2.5.2

Hi Chris,

The issue arises in an odd combination.

1. you installed VOLK (and cpu_features) to your custom prefix before
2. your custom prefix is currently NOT sourced
3. you try to re-compile with `CMAKE_INSTALL_PREFIX=<CUSTOM_PREFIX>`

What I've learned so far:
1. It requires special configuration in a submodule to disable installation.
2. CMake tries to be smart and the linker does smth different.

A more complete analysis and a subsequent fix may be nice.

Cheers
Johannes
