You can use cmake to generate the project files for the IDE you are using (VC2010, XCode, etc).
Type 'cmake --help' for available generators on your platform.

Examples for Windows with Visual Studio C++ compiler:
If using directly the cl compiler:
```
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE:string="Release" -DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX:path="C:/Users/Public" -DCMAKE_LIBRARY_PATH:path="C:/Users/Public" -DCMAKE_INCLUDE_PATH:path="C:/Users/Public/include" ..
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE:string="Release" -DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX:path="%USERPROFILE%" -DCMAKE_LIBRARY_PATH:path="%USERPROFILE%" -DCMAKE_INCLUDE_PATH:path="%USERPROFILE%\include" ..
```
To compile a 64-bit application, open 64-Bit Visual C\+\+ toolset on the command line and run cmake. For further information, please refer to: [How to: Enable a 64-Bit Visual C\+\+ Toolset on the Command Line](https://msdn.microsoft.com/en-us/library/x4d2c09s.aspx).
If you do not want directly use the cl compiler, you could use:
```
cmake -DCMAKE_BUILD_TYPE:string="Release" -DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX:path="C:/Users/Public" -DCMAKE_LIBRARY_PATH:path="C:/Users/Public" -DCMAKE_INCLUDE_PATH:path="C:/Users/Public/include" ..

```
To create Visual Studio solution (.sln) and project files (.vcproj / .vcxproj):
```
cmake -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE:string="Release" -DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX:path="%USERPROFILE%" -DCMAKE_LIBRARY_PATH:path="%USERPROFILE%" -DCMAKE_INCLUDE_PATH:path="%USERPROFILE%\include" ..
```
64-bit application:
```
cmake -G "Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE:string="Release" -DBUILD_SHARED_LIBS:bool=on -DCMAKE_INSTALL_PREFIX:path="%USERPROFILE%" -DCMAKE_LIBRARY_PATH:path="%USERPROFILE%" -DCMAKE_INCLUDE_PATH:path="%USERPROFILE%\include" ..
