Build target openhmd-shared does not exist

[ppaalanen]

I tried compiling this for the first time according to the readme. First I updated OpenHMD as instructed with git-pull. Then I get:

-- [19:10:38] ~/git/SteamVR-OpenHMD/build --
$ cmake ..

The build fails on missing openhmd-shared lib.

Did you clone recursively and does subprojects/openhmd/ exist? If not, git submodule update --init should help.

[ppaalanen]

I'm fairly sure I did, but that was in May it seems. The subprojects/openhmd exists and is populated but in a detached head state, gitk saying the commit corresponding to OpenHMD master branch being checked out.

I started from scratch again, and it built just fine.

When I look at the old vs. new subprojects directories, there is a ton of changes. I suspect your advice to update openhmd with git pull origin master does not work. Maybe it doesn't lead to an actual checkout since the repository is in detached head state?

Anyway, I have no problem anymore, thanks.
