the file /usr/lib64/pkgconfig/wxsqlite3.pc looks now as following and work for
the compilation. Is this ok now ?, then i will submit a new wxsqlite3.pc file upstream.
prefix=/usr
libdir=/usr/lib64
includedir=/usr/include
Name: wxsqlite3
Description: C++ wrapper around the SQLite 3.x database
URL: http://wxcode.sourceforge.net/components/wxsqlite3/
Version: 3.0.1
Libs: -L${libdir} -lwxcode_gtk2u_wxsqlite3-2.8
Cflags: -I${includedir}/wx

I need to investigate further
