CMake instructions are missing steps

[gh-andre]

README.md provides these build steps for CMake:

$ cmake --build .
$ ctest -V .
$ cmake --build . --target install

Running this on Windows from the project root just returns this error:

Error: could not load cache

You seem to be missing a step to generate project files, which would look like this:

cmake .
cmake --build .
ctest -V .
cmake --build . --target install

In most environments CMake instructions suggest creating a directory for generated files to keep build output confined in that directory. You may want to consider something like that:

mkdir build && cd build
cmake ..
cmake --build .

This, however, messes up tests and I didn't have time to look into why tests fail after this.

Thanks for reporting this. It was fixed in #298.
