cd examples
mkdir build
cd build

cmake --build 

to get exe now, cmake --build from the examples directory.

CMake throws: Error: could not load cache

Answer 1

You could try:

1. Make sure you have enough space / correct permissions etc for the generated files to be created
2. Remove all generated files e.g. CmakeCache.txt and re-run cmake ..; check the output carefully for potential issues during this step, missing libraries etc.

Answer 2

I guess you didn't configure your project.

1. You first need to run cmake . at the project root to generate build files. You can also run it from an empty directory to separate source and build files.

2. Then you can use cmake --build ./ in the build dir.

Or, if you prefer code-only:

cd [root-directory-of-your-project]
cmake .
cmake --build ./
