Olive: Despite opencolorio is installed .... ERROR: OpenColorIO development package not found

[vibrion121]

Why qmake cant find OpenColorIO? Its installed in /usr/local/include (and is present in olve.pro)

[itsmattkc]

Try cmake instead.

Which ocio config is set to be default in Olive? I am using the Blender 2.8 Config file from Blender by doing:

tools>preference>Color Management> Enable> browse.
Default ICS sRGB, display sRGB , View Default
In fact what is planned for multiple input color space in a same project? Will it have a effect node for color space conversion?

[itsmattkc]

@cgvirus Offtopic, but there is no current default config (a custom one will probably be written at some point). You can already set different input color spaces for each media file.

[sobotka]

@cgvirus I suppose it isn't well known that OCIO can be set via the CLI. For example, on *nix-like systems you should be able to do export OCIO=/path/to/the/opencolorio/config.ocio and OCIO enabled applications should support them via the environment variable.

I'm sort of hacking away on a ColorManager class, so I'm not entirely sure if @itsmattkc has the application recognizing the environment variable yet...

Regarding multiple input colour spaces, it's all handled via the OCIO configuration. Not a problem.

Alright. Thanks folks

I'm having trouble compiling Olive, and noticed that this issue has a similar problem to mine:

Try cmake -G "MinGW Makefiles" [...] or cmake -G "Ninja" [...] (substitute [...] with the rest of your command string)

[Corruptinator]

"Rest of your command string?"

I tried:

$ cmake -G "Ninja" "C:/Github/olive"

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

  Run cmake from a shell that does not have sh.exe in your PATH.

  If you want to use a UNIX shell, then use MSYS Makefiles.

I'm trying not to make myself be stupid or anything but I'm trying to make sure I haven't done anything wrong.

[Corruptinator]

Using MSYS2 MINGW 64-Bit.exe by the way

[Corruptinator]

I realized that it's not using the right generator, Its asking for Visual Studio 15 2017:

$ cmake -G "Visual Studio 15 2017" -S olive/ -B olive-debug/

Which cmake did you install? Did you run pacman -S cmake or pacman -S mingw-w64-x86_64-cmake?

Install the following:
pacman -S mingw-w64-x86_64-cmake mingw-w64-x86_64-ninja 1.9.0-1

Then use this:
cmake -G "Ninja"

[Corruptinator]

using cmake -G "Ninja":

$ cmake -G "Ninja"

This issue seems to mostly blend into #997 so I'll merge them for now.
