I worked around a similar issue to this with a project that required
wxWidgets, which using a binary to build the compile and linker flags
rathern than pkgconfig or other method.

I wrapped my whole main project in a "if(NOT BOOTSTRAP_WXWIDGETS)" build
the project. If BOOTSTRAP_WXWIDGETS it true, then it skips the main build
and builds wxWidgets instead. You still have to run cmake and make twice,
but it works.
