CMAKE error

[nmanjofo]

I am trying to build the plugin, but CMAKE seems to complain... (I recursively cloned the latest snapshot, set BOOST_INCLUDE_DIR to boost and CMAKE_PREFIX_PATH to jsoncpp)

There are a couple different problems demonstrated here. Let's tackle them one at a time:

1. First, we're looking for the vrpathreg.exe program and attempting to parse its output. It appears that we're not finding this program on your system. Where does this program live on your computer? (It's usually in C:/Program Files (x86)/Steam/steamapps/common/SteamVR/bin/win32/, but you may have it on another directory.)
   Since we're not finding that program, as a fallback, we attempt to read directly from the openvrpaths.vrpath file. This is usually located in the C:\Users\YOUR_USERNAME\AppData\Local\openvr directory.
2. The second issue is a bug on my part. I think I've just fixed this in the cleanup branch if you'd like to test it. The cmake/cmake-3.3.0-modules/WriteCompilerDetectionHeader.cmake file was looking in a hard-coded path for a couple of the modules it wanted to include when it should've been looking in the main CMake modules directory. The fix should just be replacing the following two lines:

include(${CMAKE_CURRENT_LIST_DIR}/CMakeParseArguments.cmake)
include(${CMAKE_CURRENT_LIST_DIR}/CMakeCompilerIdDetection.cmake)

with these two lines:

include(CMakeParseArguments)
include(CMakeCompilerIdDetection)

Questions

Your responses to the following questions will help me improve the code that finds the vrpathreg program and parses the information it provides:

1. Where does the vrpathreg.exe program live on your computer?
2. When you run that program in a command prompt window, what does it output?
3. Where does the openvrpaths.vrpath file live on your computer?
4. What are the contents of that file? (You can open it in Notepad.)

Thanks!

D:\hry\steam\steamapps\common\SteamVR\bin\win64

There are actually two, one in win64, the other in win32.

Runtime path = D:\hry\steam\steamapps\common\SteamVR
Config path = D:\hry\steam\config
Log path = D:\hry\steam\logs

C:\Users\pc\AppData\Local\openvr
