Subject: [PATCH] build system: Detect POSIX regex lib more properly

Previously, if the regex lib has to be linked separately, as in the case
of MinGW/libgnurx, it is not detected properly, and build fails for shared
lib.

The imported FindRegex.cmake file is from
https://raw.githubusercontent.com/dubourg/openturns/master/cmake/FindRegex.cmake
and is licensed under the LGPL 3, same as this library.
