I’m trying to compile a lib (Anjay LwM2M) that I got from github, but the following message is displayed at the terminal:  
C:\Projetos\Anjay\Anjay\>cmake .  
– Building for: NMake Makefiles  
CMake Error at CMakeLists.txt:10 (project):  
Running

‘nmake’ ‘-?’

failed with:

no such file or directory

CMake Error: CMAKE\_C\_COMPILER not set, after EnableLanguage  
– Configuring incomplete, errors occurred!

It’s the first time I used Cmake, so I’m unaware of the cause. Thanks for any kind of support.
