- CMakeCache changes should be applied via Reload CMake project button in the tool window.
- CLion now builds only one configuration at a time (Release, Debug, etc. as configured in Preferences/Settings | Build, Execution, Deployment | CMake).
- CLion supports only GNU toolchain, that means only GCC and Clang compilers on Linux and OS X, and MinGW (or MinGW-W64) and Cygwin x64 toolchains on Windows.
Note: If you are using Visual Studio for C++ development (and Visual C++ Compiler), try our ReSharper for C++.
