This is documented:

<a href="http://doc.qt.io/qt-5/cmake-manual.html">http://doc.qt.io/qt-5/cmake-manual.html</a>

<pre><code>The easiest way to use CMake is to set the CMAKE_PREFIX_PATH 
environment variable to the install prefix of Qt 5
</code></pre>

Do this

<pre><code>export CMAKE_PREFIX_PATH=/home/user/Programs/&lt;other_stuff&gt;
</code></pre>

where references the compiler etc, so that this complete path is valid:

<pre><code>/home/user/Programs/&lt;other_stuff&gt;/bin/qmake*
</code></pre>

Well, here you have a solution for Windows: <a href="https://stackoverflow.com/questions/15639781/how-to-find-qt5-cmake-module-on-windows">How to find qt5 CMake module on windows</a>

<pre><code>set (CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.0.1\\5.0.1\\msvc2010\\")
</code></pre>

For your environment, I think you will have to change the path where Qt is located... 

Maybe this will help you:

For ubuntu:

<code>/home/ryan/Qt/</code> is the Qt installation root path

I don't know a lot about cmake, I'm trying to build a client using cmake and Qt. Getting the following error:

<blockquote>
 CMake Error at alethzero/CMakeLists.txt:26 (find_package): By not
 providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project 
 has asked CMake to find a package configuration file provided by 
 "Qt5Widgets", but CMake did not find one.
 
 Could not find a package configuration file provided by "Qt5Widgets"
 with any of the following names:

<pre><code>Qt5WidgetsConfig.cmake
qt5widgets-config.cmake
</code></pre>
 
 Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or
 set "Qt5Widgets_DIR" to a directory containing one of the above
 files. If "Qt5Widgets" provides a separate development package or
 SDK, be sure it has been installed.
 
 -- Configuring incomplete, errors occurred!
</blockquote>

As far as I understand, I need to add the QT path to CMake. How do I do it? I have Qt installed in /home/user/Programs. All the explanations I find are "just do this or that". I need the exact Terminal commands so I can just learn how to do it in the future.

Thanks!

UPDATE: <code>export CMAKE_PREFIX_PATH=/home/user/Programs</code> did not help me.

Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH
