CMake file for both Linux and Windows

[Era]

With VS2017 supporting CMake files, and my none love for Code::Blocks I have written a CMake file that works on both Linux and Windows.(I have not tested the $ENV{HOME} yet, I had that hard coded).

 

There is one issue I know of where VS2017 does not seem to obey the CMAKE_RUNTIME_OUTPUT_DIRECTORY line and puts the binaries in a folder called Debug or Release in side your project directoy. You can safely move them out to the top level.

EDIT: Minor changes to help clean it up some. Also tested the $ENV{HOME} and it does indeed work.

EDIT2: Added a file glob for shaders and scripts so if you are using an ide like qt-creator they will show up in the project view.

So while playing with this some more it seems that VS2017 can only do debug builds due to a bug on how it defines CMAKE_BUILD_TYPE.

 

 

EDIT:

 

Found a work around. Under the "cmake->change cmake settings" menu click any option and replace the file with this:

 

{
   // See https://go.microsoft.com//fwlink//?linkid=834763 for more information about this file.
   "configurations": [
    {
    "name": "x86-Debug",
    "generator": "Visual Studio 15 2017",
    "configurationType" : "Debug",
    "buildRoot":  "${env.LOCALAPPDATA}\\CMakeBuild\\${workspaceHash}\\build\\${name}",
    "cmakeCommandArgs":  "-DCMAKE_BUILD_TYPE=Debug",
    "buildCommandArgs": "-m -v:minimal"
    },
  {
    "name": "x86-Release",
    "generator": "Visual Studio 15 2017",
    "configurationType": "Release",
    "buildRoot": "${env.LOCALAPPDATA}\\CMakeBuild\\${workspaceHash}\\build\\${name}",
    "cmakeCommandArgs": "-DCMAKE_BUILD_TYPE=Release",
    "buildCommandArgs": "-m -v:minimal"
  },
  {
    "name": "x64-Debug",
    "generator": "Visual Studio 15 2017 Win64",
    "configurationType": "Debug",
    "buildRoot": "${env.LOCALAPPDATA}\\CMakeBuild\\${workspaceHash}\\build\\${name}",
    "cmakeCommandArgs": "-DCMAKE_BUILD_TYPE=Debug",
    "buildCommandArgs": "-m -v:minimal"
  },
  {
    "name": "x64-Release",
    "generator": "Visual Studio 15 2017 Win64",
    "configurationType": "Release",
    "buildRoot": "${env.LOCALAPPDATA}\\CMakeBuild\\${workspaceHash}\\build\\${name}",
    "cmakeCommandArgs": "-DCMAKE_BUILD_TYPE=Release",
    "buildCommandArgs": "-m -v:minimal"
  }
   ]
}

 

The only thing changed is the cmakeCommandArgs where we pass in the correct way to define the build type.
