[vcpkg] vcpkg_configure_meson not respecting VCPKG_C(XX)_FLAGS?

[Neumann-A]

Seems like vcpkg_configure_meson is not respecting VCPKG_C(XX)_FLAGS

It should probably do exactly the same as vcpkg_configure_cmake which is simply loading a toolchain file and then set the flags accordingly. this way the flags are only ever set in one location. The same is probably true for vcpkg_configure_qmake where flags have to be passed via: QMAKE_CXXFLAGS+= etc.
