Yes. It shouldn't matter though.

Did you try running cmake-gui from a Visual Studio

No, it's not necessary, and you don't have to list them. In fact, I didn't

I don't think you're supposed to set PREFIX to a system path. To avoid
needing root to configure and compile among other things.
I always set PREFIX to CMAKE_BINARY_DIR and so far I can't imagine any
reason to ever set it to anything else.

You can override parts of PREFIX with these
TMP_DIR = prefix/tmp
STAMP_DIR= prefix/src/name-stamp
DOWNLOAD_DIR = prefix/src
SOURCE_DIR = prefix/src/name
BINARY_DIR = prefix/src/name-build
INSTALL_DIR = prefix

libB depends on libC and libC depends on libB.
How is that even possible? You compile B and it fails because there's no C
yet. You compile C and it fails because there's no B yet.

If I guessed right, your problem is linker errors when building your
project. My solution is to just manually add whatever extra
target_link_libraries are needed to shut the linker up and move on.

Uh, why are you talking about STREQUAL when the problem is with set(baz

How about something like this:
if(${CMAKE_BUILD_TYPE STREQUAL DebugAndRelease)
include(ExternalProject)
ExternalProject_Add(MEDEBUG
CMAKE_FLAGS -DCMAKE_BUILD_TYPE Debug)
ExternalProject_Add(MERELEASE
CMAKE_FLAGS -DCMAKE_BUILD_TYPE Release)
install(FILES ...)
In case you haven't thought of it, you could run actual Linux in VirtualBox
and not have to deal with cross compilation.

If I have a dependency (e.g. SDL2) that seems to work with add_subdirectory
just fine, should I still use ExternalProject_Add instead? Given both ways

I'm just learning CMake and posting questions in this mailing list, but the
answers I get only confuse me. It seems I must take a step back and ask
more general questions.
In Linux there is a package for everything, so you just find_package
whatever you need.
But on Windows most libraries exist

As a last resort, here's my specific problem: I want to compile and run a
hello world SDL2 application on Windows, Linux, and OS X - purely as an

SDL2 only exists in source form in their repository.

I use add_subdirectory to add bullet and sdl.. Could you try that?
That's what I tried initially, but another external project dependent on
Bullet, btOgre, failed to find_package(Bullet). I think it's because when
CMake configures btOgre it expects Bullet binaries to be built and
installed
There is no Bullet package for Ubuntu. But most importantly there is no
such thing as packages in Windows. So I have to build it into my app.
I also want to avoid having to alter the CMake files of my dependencies. I
want other devs to be able to just check out the latest version of Bullet
