Cmake -我必须运行Cmake -build.两次用于构建二进制文件

Question

我有一个柯南和Cmake的问题:

与柯南我下载我的库，我想用Cmake编译，这是我的CMakeLists.txt:

cmake_minimum_required(VERSION 3.16)
project(BABEL)
set(CMAKE_CXX_STANDARD 20)
set(PROJECT_NAME BABEL)
set(SOURCES qt/main.cpp)
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
include(${CMAKE_BINARY_DIR}/conan_paths.cmake)
conan_basic_setup(KEEP_RPATHS)
if (APPLE)
set(CMAKE_INSTALL_RPATH "@executable_path/../lib")
endif (APPLE)
file(WRITE ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/qt.conf [Paths]nPrefix=${CONAN_QT_ROOT})
add_executable(${PROJECT_NAME} ${SOURCES})
find_package(portaudio REQUIRED)
find_package(opus REQUIRED)
find_package(Qt5 COMPONENTS Widgets Network Core Gui REQUIRED)
target_link_libraries(${PROJECT_NAME} ${CONAN_LIBS})
target_link_libraries(${PROJECT_NAME} opus)
if (WIN32)
target_link_libraries(${PROJECT_NAME} portaudio_x64)
else()
target_link_libraries(${PROJECT_NAME} portaudio)
endif()

如果我写这个命令:

mkdir build && cd build && conan install .. && cmake .. -G "Unix Makefiles" && cmake --build.

我必须写cmake——build。第二次构建二进制文件时，知道我在这里做错了什么吗?

下面是构建的结果:

The package name passed to `find_package_handle_standard_args` (Opus) does
not match the name of the calling package (opus).  This can lead to
problems in calling code that expects `find_package` result variables
(e.g., `_FOUND`) to follow a certain pattern.

我不能放完整的结果。

所以很明显，当把所有的命令写在一起的时候有一个bug，一个一个的输入解决了这个问题。
