tried
cmake -DHPX_DIR=$HOME/build/hpx_buildidle ~/hpx_miniapps/miniapps/MiniGhost

which gave me this error:

CMake did not find one.

Could not find a package configuration file provided by "HPX" with any of
the following names:

HPXConfig.cmake

Add the installation prefix of "HPX" to CMAKE_PREFIX_PATH or set "HPX_DIR"
to a directory containing one of the above files. If "HPX" provides a
separate development package or SDK, be sure it has been installed.

HPX_DIR does not point to the correct path.
Please consult the documentation:
http://stellar-group.github.io/hpx/docs/html/hpx/manual/build_system/using_hpx/using_hpx_cmake.html

look for HPX_DIR.

Does this solve your problem?

cmake -DHPX_DIR=$HOME/build/hpx_buildidle/lib/cmake/hpx ~/hpx_miniapps/miniapps/MiniGhost

built it in /src

doesn't seem to matter since it won't run but that's another issue

How do I direct where the binary is built

This is done via cmake. Why is that important? It needs to be done by the project that is compiling that executable (Look into CMake's output paths). That's not a problem of HPX though.

Is all of this properly documented in our docs?

Is this really something we need to document? It's something quite specifc to the external project itself and should be documented there instead of documented in the HPX docs.

I think we should document how to build external projects with HPX and
what needs to be done to make those apps run properly.

The external build support is explained in those two sections:
http://stellar-group.github.io/hpx/docs/html/hpx/manual/build_system/using_hpx.html

What's missing (please also see #1247 which should get fixed until 0.9.9)?

By default CMake places the binaries in the directory where you call add_executable or similar.
If you want to have them placed in bin or lib or similar, you can do so by tell cmake via the *_OUTPUT_DIRECTORY variables.
The HPX build system does this in the cmake/HPX_SetOutputPaths.cmake. This script is not included by default in external builds, because we can't guess what the resulting layout of an external project will be. To mimic HPX's behaviour, you can do so by adding include(HPX_SetOutputPaths) after find_package(HPX).
