+# Building libqpsd for nomacs
+
+## Build libqpsd (Windows)
+
+### Compile dependencies
+
+- [Qt](https://www.qt.io/)
+
+### Compile LibQPSD
+
+- copy `CMakeUserPathsGit.cmake` and rename it to `CMakeUserPaths.cmake`
+- add your library paths to the `${CMAKE_PREFIX_PATH}` in `CMakeUserPaths.cmake`
+- Open CMake GUI
+- set this folder to `where is the source code`
+- choose a build folder (e.g. `build2017-x64`)
+- Hit `Configure`then `Generate`
+- Open the Project
+- Compile the Solution (build Release and Debug)
+- Build `INSTALL`
+- You should now have a `qpsd.dll` in $YOUR_QT_PATH$/plugins/imageformats
+- nomacs will automatically copy the plugins from there to it's build folder
+
+## Build libqpsd (Ubuntu)
+
+install dependencies
+```bash
+    sudo apt-get install debhelper cdbs qt5-qmake qttools5-dev-tools qt5-default qttools5-dev libqt5svg5-dev qt5-image-formats-plugins cmake 
+```
+cd to this directory, then configure the project:
+```bash
+mkdir build
+cd build
+cmake ..
+```
+and compile:
+```bash
+make
+```
