Parts of it based on: https://gist.github.com/HiImJulien/3eb47d7d874fe5483810bd77940e74c0
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
- Clang Version 10
|
||||||
|
- Visual Studio Build Tools: https://visualstudio.microsoft.com/downloads/
|
||||||
|
- Qt5: https://download.qt.io/official_releases/qt
|
||||||
|
|
||||||
|
|
||||||
|
## Instructions Linux
|
||||||
|
|
||||||
|
### Requirements:
|
||||||
|
|
||||||
|
- Qt5 development packages
|
||||||
|
- Clang 10
|
||||||
|
|
||||||
|
### Steps
|
||||||
|
|
||||||
|
- Copy MSVC build tools into the project directory:
|
||||||
|
- Copy `C:/Program Files (x86)/Microsoft Visual Studio/2019/BuildTools/VC/Tools/MSVC/<MSVC Version>` to `msvc_build_tools/MSVC`
|
||||||
|
- Copy Windows SDK into the project directory:
|
||||||
|
- From `C:/Program Files (x86)/Windows Kits/10` copy the folders
|
||||||
|
* `Include` to `msvc_build_tools/Kit`
|
||||||
|
* `Lib` to `msvc_build_tools/Kit`
|
||||||
|
- Both directories have sub directories with the Windows SDK Version as
|
||||||
|
name.
|
||||||
|
- Adjust `clang_windows_toolchain.cmake` to use the proper Windows SDK
|
||||||
|
Version in variable `WINSDK_VER`
|
||||||
|
- Copy the Qt5 msvc development files into the project directory:
|
||||||
|
- Copy `C:/Qt/Qt5.12.10/5.12.10/msvc2017_64` to `qt5_msvc2017_64`
|
||||||
|
- Configure project using:
|
||||||
|
`cmake -DCMAKE_TOOLCHAIN_FILE=clang_windows_toolchain.cmake <project dir>`
|
||||||
|
|
||||||
