cmake building a project with conan files generates an error

I'm trying to run a project for an example of the Oat++ framework by loading libraries using conan.

My algorithm of actions:

1. In the project directory, I run the command

conan install  . --output-folder=build --build=missing 

(after this command, the conan_toolchain.cmake file is created in the ./build)

2. In the ./build directory, I run the command

cmake .. -DCMAKE_TOOLCHAIN_FILE=build/conan_toolchain.cmake

I am a beginner in this topic, I will be glad of any help!

conanfile.txt:

[requires]
oatpp/1.3.0
oatpp-swagger/1.3.0
oatpp-websocket/1.3.0
oatpp-openssl/1.3.0

[generators]
CMakeToolchain
CMakeDeps

CMakeLists.txt:

The structure of the OATTP_STARTER project:

./build
./src
./test
CMakeLists.txt
conanfile.txt

In directories ./src and ./test have other directories and project files.

At the cmake build stage with the command

cmake .. -DCMAKE_TOOLCHAIN_FILE=build/conan_toolchain.cmake 

I get an error:

CMake Warning:
  Ignoring extra path from command line:

   ".cmake"

================================================================

The above problem has been solved (namely, the cmake build error has disappeared). However, another problem has appeared

This time I tried to find information about this case, but I couldn't. As far as I understand, conan files seem to be unavailable. Do you have any thoughts on this?

In my case, @drodri's advice helped:In command line you might also quote -DCMAKE_TOOLCHAIN_FILE="build/conan_toolchain.cmake", as it seems this is a terminal command line parsing issue
