\subsection linux_using_cmake Compiling OpenMesh using CMake
In order to compile %OpenMesh, create a directory named e.g. "build" in
OpenMesh's root directory. <b>Change to the newly created directory</b> and type
<br/><br/>
<tt>
cmake .. ## Generates the appropriate Makefiles<br>
make ## Builds the project<br>
</tt><br>
\warning If your compiler does not support c++11 natively, you might have to enable it by changing the cmake call to: <br>
<tt>cmake .. -DCMAKE_CXX_FLAGS=-std=c++98</tt>
You can choose the build type by using cmake with the flag<br>
<b>-DCMAKE_BUILD_TYPE=(Debug|Release)</b> The default is: Release <br>
Other flags are:<br/>
<b>-DBUILD_APPS=OFF</b> to disable build of applications and<br/>
<b>-DCMAKE_INSTALL_PREFIX=<path></b> to specify the install path.<br/>
When calling <b>make install</b> cmake will install %OpenMesh into this
directory using the subdirectories lib/include/bin.
CMake builds both shared and static under Linux.
Everything will then be build in the <b>Build</b> subdirectory containing the libraries in <b>lib</b> and the binaries in <b>bin</b>.
There are some additional targets:<br>
<b>doc</b>: Builds the Documentation<br>
<b>doc-install</b>: Builds the Documentation and installs it<br>
<br>
\note When you link against the static libraries of OpenMesh and get the error "can not be used when making a
shared object; recompile with -fPIC" you need to add "-fPIC" to the CMAKE_CXX_FLAGS. (This is usually added automatically)

\subsection windows_using_cmake Compiling OpenMesh using CMake
Building OpenMesh on Windows requires cmake to generate the project files for Visual Studio.
<ul>
<li> Get Visual Studio ( 2013-2017 ) </li>
<li> Extract %OpenMesh source code. </li>
<li> Get all required libraries and install them ( including headers! ).</li>
<li> Download and install cmake: <a href="https://cmake.org/download/">www.cmake.org</a>.<br> </li>
<li> Start the cmake gui and open the %OpenMesh toplevel directory as source directory </li>
<li> Choose a build directory (e.g. create a directory called "build" in OpenMesh's root folder) </li>
<li> Click on configure .... If any libraries are left unconfigured, you can adjust the path manually. Rerun configure until everything is configured correctly. <br>
Attention: Some build variables are only visible in advanced view mode. Select Visual Studio 9 (2008), Visual Studio 10(2010), Visual Studio 11 (2012), Visual Studio 12 (2013) (Depending on your version) as
generator. </li>
<li> Click generate to create the visual studio project files </li>
<li> You can now find a Visual Studio solution file (OpenMesh.sln) in the <b>build</b> directory you chose in cmake </li>
<li> Now you can build %OpenMesh from within Visual Studio using the newly created project file. </li>
</ul>

\subsection mac_using_cmake Compiling OpenMesh using CMake
We recommend you to use CMake >= 3.7 as build system. This can also easily be installed
via MacPorts as well as the Qt >= 5.6 library which is used for some example applications
in %OpenMesh.<br/>
Once installed, change to %OpenMesh's root directory and create a directory
named e.g. "buildDebug" (assuming you want to build with debug symbols).<br/>
Then type in the following command to initially set up the build environment:
<br/><br/>
<tt>
cmake .. ## Generates the appropriate Makefiles<br>
</tt>
<br/>
Note: If the build directory is not a subdirectory of %OpenMesh's root folder, replace ".." with %OpenMesh's
absolute (or relative) path.
In order to manually set specific build variables, just type:

If you want to use cmake to build your Visual Studio 2008 solution file,<br>
download and install CMake from <a href="http://www.cmake.org/cmake/resources/software.html">www.cmake.org</a>.<br>
(Note: This is not mandatory since there are already VS2008 solution files included in %OpenMesh).<br><br>
<ul>
<li> Get Visual Studio ( 2008-2013 ) </li>
<li> Extract %OpenMesh source code. </li>
<li> Get all required libraries and install them ( including headers! ).</li>
<li> Get cmake for windows from http://www.cmake.org/cmake/resources/software.html </li>
<li> Start the cmake gui and open the %OpenMesh toplevel directory as source directory </li>
<li> Choose a build directory (e.g. create a directory called "build" in OpenMesh's root folder) </li>

Note: Set the CMAKE_BUILD_TYPE variable to "Release" if you want %OpenMesh to be built as release.
In Visual Studio choose "Release" in the appropriate select box and build the solution afterwards.
