Just to clarify... when I said 'when it gets installed', I mean that
wxWidgets gets installed during the build, to a prefix inside the
CMAKE_CURRENT_BINARY_SOURCE, not in install time. I'm doing it this way
to make compilation of my project dumb-proof. If wxWidgets isn't
installed, we compile our version statically and use it. When the main
target is run, wxWidgets is compiled and installed to an internal
prefix, that is.
