Trying to build samples/mqtt/basic_pub_sub sample from aws-iot-device-sdk-cpp-v2 which contains CMakeList.txt:
cmake_minimum_required(VERSION 3.1)
# note: cxx-17 requires cmake 3.8, cxx-20 requires cmake 3.12
project(basic-pub-sub CXX)
file(GLOB SRC_FILES
"*.cpp"
)
add_executable(${PROJECT_NAME} ${SRC_FILES})
set_target_properties(${PROJECT_NAME} PROPERTIES
CXX_STANDARD 14)
#set warnings
if (MSVC)
target_compile_options(${PROJECT_NAME} PRIVATE /W4 /WX /wd4068)
else ()
target_compile_options(${PROJECT_NAME} PRIVATE -Wall -Wno-long-long -pedantic -Werror)
endif ()
find_package(aws-crt-cpp REQUIRED)
target_link_libraries(${PROJECT_NAME} AWS::aws-crt-cpp)
Trying to build: mkdir build cd build cmake ..
Got errro:

CMake Error at CMakeLists.txt:21 (find_package):
By not providing "Findaws-crt-cpp.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"aws-crt-cpp", but CMake did not find one.
Could not find a package configuration file provided by "aws-crt-cpp" with
any of the following names:
aws-crt-cppConfig.cmake
aws-crt-cpp-config.cmake
Add the installation prefix of "aws-crt-cpp" to CMAKE_PREFIX_PATH or set
"aws-crt-cpp_DIR" to a directory containing one of the above files. If
"aws-crt-cpp" provides a separate development package or SDK, be sure it
has been installed.
-- Configuring incomplete, errors occurred!
I found aws-crt-cpp-config.cmake if folder home\a\cpp_projects\sdk-cpp-workspace\lib\aws-crt-cpp\cmake
But how to tell about it to CMake?
