I have found the solution. While the Visual Studio IDE installed successfully it did not install any build tools and therefore did not install the C++ compiler.

By attempting to manually <a href="https://msdn.microsoft.com/en-us/library/ms235629.aspx" rel="noreferrer">create a C++ project in the Visual Studio 2015 GUI</a> I was able to prompt it to download the C++ packages. CMake was then able to find the compiler without any difficulty.

was defined as

<pre><code>PROJECT( projname CXX )

Somehow, CMake does not recognize

<pre><code>PROJECT(sub_project_name CXX C)

since the C compiler is not set in the parent.

I solved the issue by using

<pre><code>PROJECT( projname CXX C)

in my main <code>CMakeLists.txt</code> file.

Look in the Cmakelists.txt if you find ARM you need to install C++ for ARM and as well vcvarsall.bat use for ARM bin folder.

It's these packages: 

C++ Universal Windows Platform for ARM64 "Not Required"

Visual C++ Compilers and libraries for ARM "Not Required"

Visual C++ Compilers and libraries for ARM64 "Very Likely Required"

<pre><code>Required for finding Threads on ARM 
enable_language(C) 
enable_language(CXX)
</code></pre>

Then the problems might disappear: 

No CMAKE_C_COMPILER could be found.

No CMAKE_CXX_COMPILER could be found.

If above does not resolve your problem?

Optionally you can remove the options C and CXX in cmakelists.txt by setting # infront of where the enable_language(C) is. And avoid Android ARM processor compilation.

This question is old, but none of the solutions here were working for me. I'm using Visual Studio 2019, and in my case, C++ compilation was working but just broke one day.
However, I noticed that there was an update ready to be installed in the Visual Studio Installer.
After installing that update, rebooting my computer, and relaunching Visual Studio, all of the C++ CMake problems disappeared. I'm not quite sure why this fixed it, and I can only speculate, but I can only assume that one of two things occurred. Either installing that update fixed a broken installation, or the update was quietly downloaded and prepared in the background, breaking things in the process.

After installing Visual Studio 2015 and running CMake on a previous project, CMake errors stating that it could not find the C compiler.

<pre><code>The C compiler identification is unknown
The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:4 (PROJECT):
 No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:4 (PROJECT):
 No CMAKE_CXX_COMPILER could be found.
</code></pre>

I went searching for <code>cl.exe</code> in the Visual Studio folder,<code>C:\Program Files\Microsoft Visual Studio 14.0</code>, and could not find it. 

How do I set up CMake to work on Windows with Visual Studio 2015?
