Unknown CMake command "sugar_include".

[Yiltan]

Hello C3SR Team,

I am getting the following error when building your project:

CMake Error at CMakeLists.txt:11 (sugar_include):
  Unknown CMake command "sugar_include".

I was wondering if anybody would have any suggestions on what this could be.

When you clone scope and enable Comm|Scope, and build for the first time, you should see something like this in the CMake output:

-- [hunter] SUGAR_ROOT: /home/pearson/.hunter/_Base/51d2d6b/9b2c9d4/d68db6d/Install (ver.: 1.3.0)
-- [hunter] Building sugar

...

If you're re-running cmake after some changes, you should see just something like this:

-- [hunter] Calculating Toolchain-SHA1
-- [hunter] Calculating Config-SHA1
-- [hunter] HUNTER_ROOT: /home/pearson/.hunter
-- [hunter] [ Hunter-ID: 51d2d6b | Toolchain-ID: 9b2c9d4 | Config-ID: d68db6d ]
-- [hunter] SUGAR_ROOT: /home/pearson/.hunter/_Base/51d2d6b/9b2c9d4/d68db6d/Install (ver.: 1.3.0)
...

This is when sugar gets installed, and you should be able to find a sugarConfig.cmake in there if it gets installed correctly (the path may be a bit different on your system), but you can find it in SUGAR_ROOT above

$ ls ~/.hunter/_Base/51d2d6b/9b2c9d4/d68db6d/Install/lib/cmake/sugar
sugarConfig.cmake

Is there any error in the part of the cmake output related to downloading and installing sugar?

I don't seem to get the first few lines related to sugar that you do. The complete output is below. I am running the command mkdir build && cd build && cmake .. -DENABLE_COMM=1 before the error arises. I am using the git tag labeled as v0.8.2.

I usually work with GNU Make so cmake is slightly different to me. I appreciate the help.

You're starting here: https://github.com/c3sr/scope ? And then mkdir build...?

Ah sorry, I was trying to directly build Comm|Scope. I now see that this is a submodule within a larger project. I've built it from Scope and now things work as expected.
