* fix configure meson for non windows builds.
* change to the two ports using meson
* fix passing of empty compiler arguments.
* dont transform / into - for all flags
* copy meson logs into the buildtree to better diagnose CI errors of meson ports
* another change to the two ports to actually force a CI rebuild
* add missing /pkgconfig dir to PKG_CONFIG_PATH
* fix pkgconfig setup
* add share/pkgconfig to PKG_CONFIG_PATH
* Add CMake path to PATH for meson
* add share folder to prefix for meson
* remove double message
* add libdir so that meson does not install into architecture folder in linux
and make prefix path target dependent. (Or should it be host dependent?)
* bump controls
* update toolchain selector to use VCPKG_TARGET_IS_<paltform>.
* change pkgconfig prefix and path.....
meson is not correctly handling native windows paths and eating "\"
PKG_CONFIG_PATH also nees : to correctly separate paths
Prefix still must be near to native path but with / instead of \ C:/somepath/
